Thanks for the CC, Ms2ger.  Seems likely to be a regression from bug 972591.

I looked at 6 reports, and they all had the Yahoo toolbar.  This sounds like a startup crash, so I'll install it and try to reproduce.

STR: install Yahoo toolbar, open and close the browser a few times (presumably so you start hitting the startup cache).

I landed a backout of part 3 of bug 972591, and confirmed that that fixes the crash.  We still hit the same failure path with the backout, it just doesn't cause a crash.

Will go ahead and track this for now so we can keep and eye on it.

Relanded part 3 of bug 972591 and no crashes since then.

yes, no more crashes since the relanding.
