Looks like your build lacks the symbols needed for a stack trace to be useful.  Can you build your own using the instructions at http://developer.mozilla.org/en/Mac_OS_X_Build_Prerequisites?  Should take 1-2 hours.  The default setup (a debug build) is fine, since we're not after precise timing data, but you can build optimized if you want.

Then, instead of a random crash dump, please get a sample using Activity Monitor.

No reply, INCO. Please reopen if you still see this bug in Firefox 3.5 or later in Firefox safe mode (http://support.mozilla.com/en-US/kb/Safe+Mode) or a new Firefox profile (http://support.mozilla.com/en-US/kb/Profiles) with updated plugins.
