Bug#638903: iceweasel refuses to start after upgrade

[Svante Signell]

Package: iceweasel
Version: 6.0-2
Severity: serious

iceweasel refuses to start after upgrade to 6.0. This is the second
computer having the same problem. Is this known? On the other computer I
had to create a new account, and restore by coping the bookmark file:
bookmarks-2011-08-22.json and the settings file:sessionstore.js
manually.
