Bug#593441: iceweasel: Can not close tabs - sometimes.

[Bolli]

Package: iceweasel
Version: 4.0~b3-0
Severity: important

After about 3 minutes of running  Iceweasel/4.0b3 (64bit), I loose the
functionality to close tabs.
Either if I hit the little X on the tab, CTRL+W or whatever, the tab still sits
there like nothing ever happend.

Running  Iceweasel 4.0b3 from the terminal and regenerating the problem, does
not give any output.
