Bug 385494

I was hitting tab (repeatedly and a tad furiously I guess) to complete a directory name in the file selector, in order to find a patch to upload it to bugzilla. Firefox crashed, and the backtrace points to an assertion in the file selector. Unfortunately, I can't get the assertion from .xsession-errors, since it stopped logging a long time ago (too many messages from glibtop).

I have a good backtrace, though. Frame #23 looks interesting:
