Bug 310036

Application: konqueror (4.9.2)
KDE Platform Version: 4.9.2
Qt Version: 4.8.3
Operating System: Linux 3.6.6-1.fc17.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:

I've opened a link to a bugreport from kmail.
Konqueror has asked me whether this Bugzilla site is the one I want to log in with the user name "null" (I bet I've seen report of this problem somewhere already) and after closing that dialogue, I've closed Konqueror.
Then DrKonqi appeared ...

I've got a suspicion that I've hit the timeframe between displaying this dialogue for the first and for the second time and that was the condition to trigger the crash - if I would wait for the second appearance of the dialogue, closed it and closed Konqueror only after that, I'd bet it wouldn't crash, as it happened to me multiple times before. (Sometimes, the dialogue appears just once, sometimes multiple times - up to four.)

Note that there are several duplicates suggested, but these are closed, and I really have Qt > 4.6 ...

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