There have been quite a few crashes the past few days (since 1/9) on the MozillaTrunk with this stack signature. Most of the incidents are on Windows 98, but there are a couple on NT and 2K. Not sure if this is a regression, but it's worth a look into.

This looks to be a dupe of bug 188877. It should be fixed now. *** This bug has been marked as a duplicate of 188877 ***

Marking Verified Duplicate. What I'm keying off is the reference to nsDownloadManager.cpp, line 1184, in the stack trace printed above, which was the location of the fix provided for the other bug - Dave: good catch!
