TSVNCache.exe Crash (Access Violation)

Folks,

I've been having intermittent problems with TSVNCache.exe crashing with an Access Violation on my Windows 7 workstation. I'm not sure what causes the behavior, but I've downloaded symbols and attempted to do a little bit of debugging in WinDbg the last time it crashed.

This is what I've found--My debugging steps approximately follow this KB article:
http://support.microsoft.com/kb/313109

Also, I took a minidump of the crashed process (while WinDbg was attached after the crash), which is attached. (Hopefully it doesn't have my password in cleartext :))

I hope this helps. Let me know if I should file a bug?

Thanks!
-Paul B. Davis
