GMarks causing Firefox crash at shutdown

[Greg]

Hi,

I'm using Firefox-3.5.2 on 64-bit Linux (Ubuntu 9.04).

- Firefox sometimes segfaults when exiting the program
- the crash only happens when GMarks is enabled
- it doesn't happen every time, only intermittently

I've managed to create a backtrace in the debugger so hopefully
someone decipher what is going wrong. Maybe GMarks is triggering a bug
in Firefox? Thanks for your help
