Bug#641593: add project category crash resurfaced

[Rom Walton]

Here is a change that I think might resolve the issue.

I'm having problems committing it right now, SSL is going through the process of shutting down to repair an electrical short that happened a few weeks ago.

If this doesn't fix the problem I have another idea, but I think this will resolve the issue.

Thanks for a complete stacktrace and the steps you used to create it.  I didn't know about --enable-wx-debug.

Hi,

This is about the bug #641593 [1], I compiled boincmgr with "--enable-debug --enable-wx-debug". Here is the backtrace it got when reproducing the crash.
