Error message end tag and start tags dont match when publishing to flickr from lightroom 5.3

Question

I have had an ongoing problem that lightroom publishing to flickr times out frequently when uploading many photos.  However, for about the last week or two weeks i have been getting a different error message:
Error message: “Can’t update this collection.  An internal error has occurred:  End tag ‘body’ does not match the start tag ‘hr’. 
Windows 7 system.
I set up a photoset in lightroom (have tried both smart and regular photosets with same results).  These photosets can contain anywhere from 16 to 3000 or more photos. The first photos are uploaded – maybe 10, maybe 100, maybe 1000.  Then it generally seems to stop working.  Sometimes I can continue publishing new photos or republishing, sometimes I cant.  For example I currently have 11 flickr publish photosets in one lightroom catalog, with the following success numbers:
NAHCR00 total 3044, published: 1851
NAHCR01 total 748,published: all
NAHCR03 total: 532 published: all
NAHCR04  total: 412 published: all
NAHCR05 total: 340 published: 152
NAHCR07 total: 248 published: 50
NAHCR08 total: 524 published: 197
NAHCR09 total: 44 published: all
NAHCR10 total: 40 published: all
NAHCR11 total: 32 published: all
NAHCR12 total: 124 published: 4
I have succeeded in uploading over 28000 pictures from flickr (mostly from three other lightroom catalogs to several flickr account, both paid and free).  The other catalogs marks the photosets as public  and generally seems to be more successful at uploading.
All of these problem photosets are marked as private so that only I can see them.  The  photos themselves have peculiar names including many special characters including chinese characters, arabic alphabets, spaces, commas, exclamation marks etc etc.  I tried telling lightroom to rename the files to names with no special characters but it still fails.
I emailed Flickr with the above information and this was their response:
Thank you for contacting Yahoo Flickr.
I would first like to apologize for any inconvenience you have experienced while attempting to upload photos to your Flickr account.
First, Lightroom is a 3rd-party application; we can't offer any support for it. Please contact the developer of that application for help.
With that said, please note that there's a known issue with Avast's Web Shield and AVG antivirus that causes issues with uploads. If you have either of these applications, disable the "Link Scanner", add Uploadr to the exceptions list, and then try to upload. If the issue persists, temporarily turn off the anti-virus / firewall and try to upload again.
Please also see the following article on Flickr's upload limitations:
Flickr upload limitations
  Lastly, here are some general troubleshooting steps that you can try: 
Most connection issues arise due to a problem between your computer and Flickr and are often temporary. Try the following:
Briefly power off any broadband modems and routers to reset the network connection.
If you connect wirelessly, move your computer closer to the wireless access point, or 'plug in'.
If you're connected through a router, try plugging directly into the broadband modem.
See your manual for configuration options if the router is slowing or blocking uploads.
Also, try lowering your # or matching it to your ISP's value.
  Additional troubleshooting 
Try uploading with an alternate method:The web upload page, the Uploadr app, or upload by email.
If you're using an older version of Uploadr, update to the latest version.
Search our forums to see if there are any specific network hardware incompatibilities.
I realize that this isn't a satisfying response to your request, and I am sorry for that. Please let me know if I may be of further assistance, or if you have any questions or concerns.
Thank you again for contacting Yahoo Flickr.

I had the same problen with Lightroom 5 - Prepares the files but won't Upload to Blurb. Tried numerours times. It is a Landscape size Book 132 Pages. There is a BUG in Lightroom and here is how I got it to work:
Check each slide and make sure APPLY BACKGROUND GLOBALLY, GRAPHIC or BACKGROUND COLOR and not checked,. If so Uncheck them.
Go to EDIT and SELECT ALL Slides in the Book.
Select Apply Background Globally - turn it off and on several times, then leave it off
Select GRAPHIC - turn it off and then turn it on and off several times
Select BACKGROUND COLOR - turn it on then off then on then off
I ended up with APPLY GLOBALLY unchecked for Every Page.
GRAPHIC was turned on with a Graphic set at 12% Opacity on every Page
Again check each page first for these Checkmarks or just fix exverything with SELECT ALL.
Background Color was Turned off. 
NOW UPLOAD THE BOOK - It took a couple hours but it uploaded without a hitch., I turned off all Firewalls and Plugged directly into the Router. I am using an IMac 27" with 32 GB of memory and this is the only way it would work. The Mac is about 7 days old and Lightroom 5 is also 7 days old. BUGGIEST piece of software I have ever used.
Note - one of the above steps fixes the BUG - I am not sure which one but one will fix your book. It finally uploaded to BLURB today. It took a few hours though.
