Bug 223709

Application: rekonq (0.3.0)
KDE Platform Version: 4.3.90 (KDE 4.3.90 (KDE 4.4 RC1))
Qt Version: 4.6.0
Operating System: Linux 2.6.31-17-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
I had a few tabs open on the same website as I was comparing some screens. They had opened from a e-mail I had in the first window. When I was done I hit Ctrl+W to close the last three tabs leaving me with the single e-mail tab that I had started out with. As soon as the second to last tab had closed the titlebar changed to the title of the first tab but before the view could display the page the entire application closed as if I had shut it down.

 -- Backtrace:
Application: rekonq (kdeinit4), signal: Segmentation fault
