It also happens to me, I have
Mozilla/5.0 (Windows; U; Windows NT 5.1; it; rv:1.8.1.11) Gecko/20071127 Firefox/2.0.0.11 with no further extension installed.

It often crashes, let's say once every 10 use sessions, while I'm doing nothing particular, for instance when I'm on youtube... but I noticed it often crashes when I close a tab or when I open a new blank tab... Visual Studio Debug always says Access Violation and the Disassembly of the execution thread is often blocked on one of these two instructions:
6011CB7C  mov         al,byte ptr [esi] 
but esi is not null, or
027EC9E6  mov         byte ptr ds:[00000103h],al
