Application: rekonq (0.7.0)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
close rekonq 
after visiting some pages (also pdf reading) I close rekonq and it crashes, asking me to report a bug. 

Sometimes it crashes after the main window disappears, it just reports an unclean shutdown and asks me whether I want to restore the session -- which I dont, since I closed it correctly.

The crash can be reproduced every time.

-- Backtrace:
Application: rekonq (rekonq), signal: Segmentation fault
