LR2.6 Export folder to Catalog crashes

Question

I have encountered a completely reproducable error on my system. This may have existed in LR prior to 2.6, but I was finally able to isolate it and no longer have any systems running older versions.
I have a current folder of images in the catalog on my Laptop that I wish to export to a catalog for import into my desktop. Both systems have been upgraded to LR2.6 at this time.  Exporting from the laptop if I choose a long foldername/filename it can result in a complete crash of the application.Steps taken are as follows:
Choose folder of images from the navigator and right-click, choose "Export this Folder as a Catalog..."
in the next Dialog, choose a suitable location for the export and provide a long name. I used the name of the event, in this case "20091002 Calendar Release Party for UserName - Company Name @ Venue Name". At this point LR2 proceeds to create the catalog file, but as soon as file creation is complete, before the first information is exported, the application crashes, goes "light" (There is an 80% transparent white overlay) and a pop-up is provided that reads "Adobe Photoshop Lightroom 64-bit has stopped working  A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available." The only available button on that dialog is "Close Program."
Looking at the destination, the export created the initial catalog folder and inside that it created the previews.lrdata folder.  I have one initial folder and one sub-folder under that inside previews.  If I manually attempt to create a file in this folder, I am successful, but only with filenames below 25 characters (varies by folder name length). The lr-preview.noindex files have a very long GUID that far exceed the space available for naming.
When I reduced the export catalog name to a much shorter name; "20091009 Calendar Release" the problem was resolved and the export proceeded normally.  I understand that if a name is too long, the limitation is a filesystem issue, however the application should trap this error and not crash without explanation.
There are also two events logged in the Windows Application Event Log.
The first is:
Source: Application Error
Event ID: 1000
Task Category: (100)
Level: Error
Keywords: Classic
User: N/A
Faulting application name: lightroom.exe, version: 2.6.0.2, time stamp: 0x4b1940b6

Report Id: 0136db0e-edd7-11de-8bea-001eecc8c845
The second Event is an Event ID: 1001 from Windows Error Reporting containing all the same information in the WER format which is used to report the error back to Microsoft for evaluation.

Answer 1

I am using LR3.3 and had the issue of Lightroom crashing while creating a folder as a catalog.  I unchecked the dng and preview boxes and now the catalog is fine!
Best wishes and I hope Adobe makes the file names longer!
