One answer
Curious. The stack trace indicates that the failure is due to a null handle for the graphics resource. This would typically mean one of two things:
1) your system has run out of GDI objects (which is possible as we've discovered a couple of memory leaks recently that will be fixed in our upcoming release - 2.0.0.2), or
2) there's some sort of stale project page in your workspace
#2 seems unlikely given your description. #1 would generally coincide with a number of "Out of Handles" messages in the log. If it is #1, you could try shutting down the client, possibly rebooting but probably not necessary, restarting the client and immediately opening the project home page and see if it happens again.
Aside from that, is it possible there was a recent change to the members of the project, or a change about a specific user who was already a member (ie, change to their user name or id)?
