Comment 110 for bug 220628

I've had the same problem and the patch works so far, however it seems, that it also introduced a new bug.
It occurs under the same conditions as the bug that is now fixed.
So when trying to reproduce it I opened a lot (200+) tabs from Digg an Youtube and at some point a tab openes in an Untitled window outside of firefox and I get the following errors:

Whe I close that window firefox crashes, if I don't it just keeps running, occasionally opening another tab in a window...
