Photoshop CS4 11.0.1 crash upon save, leaves small sized corrupt PSD file

Question

Hi!
I've just updated our retouchers Photoshop CS4 to 11.0.1 but one of the issues we had with 11.0.0 remains. The problem doesn't happen that often, but since the result is an unusable .PSD file it's pretty nasty...
Sometimes when saving Photoshop crashes and the .PSD that was to be saved becomes a small (68 KB in the last example) and unusable.
The hardware/software we have:
Mac Pro 2.66 GHz (some with 5 GB RAM and some with 9 GB RAM)
Mac OS X 10.5.6
Photoshop CS4 Standard (updated to 11.0.1)
People work on server volumes shared via AFP. I've heard saving over the network isn't supported, but there's no other way, plus this issue never happened in CS3 so...
Any ideas on what can be done?
Below is the latest crash log:

Answer 1

This is the boilerplate text I use in connection to saving to a network (please NOTE the part where it explains that
normally, it does work
, but that it is impossible to troubleshoot someone else's network remotely, and that's why it's not supported by Adobe):
If you are opening files over a network or saving them to a network server, please
cease and desist immediately
in the event you are currently experiencing problems with one or more files.
Working across a network is not supported.
See:
http://www.adobe.com/support/techdocs/322391.html
Copy the
CLOSED file from your server to your local hard disk, work on it, save it again to your local hard disk, close it, and copy the closed file back to the server.
Of course, the fact that Adobe does not support working across a network does not necessarily mean it won't work. It should.
Adobe's position is that there are too many variables in a network environment for them to guarantee that everything will work correctly in every network, especially given the fact that if something does
not work properly, it's probably the network's fault, and Adobe has no way of troubleshooting your network.
If you can't work locally, you are on your own, and if something happens, you're on your own. If you must work from a server, make sure your network administrator is a competent professional.
When problems arise, a lot of valuable work can be lost.
