Restoring windows and tabs causes crash on exit

0. Extract TBB 3.5.1
1. In Torbutton, uncheck Don't record browsing history
2. In Firefox options, set startup to Show my windows and tabs from last time
3. Close TB
4. Open and close TB a few times
5. Open and close TB. It will crash on exit, every time.

Tested on Windows 7 64bit. This does not happen in a TBB with Firefox 17.
