Sentry Crash Report:

Description Roger Pixley 2011-08-22 22:33:03 UTC 
Application: konqueror (4.7.00 (4.7.0))
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.3
Operating System: Linux 2.6.40-4.fc15.i686 i686
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
Opening Konqueror or Rekonq and loading a HTML page crashes it. An Image or PDF will not.

- Unusual behavior I noticed:
Other than the crash itself not a lot

- Custom settings of the application:
This started on the same day that I installed Adobe Flash (though not at the same time) and has persisted even after removing Flash.

The crash can be reproduced every time.

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

Comment 2 Dawit Alemayehu 2011-11-21 19:59:33 UTC 
@adria: first your crash has nothing to do with the crash in this original report and secondly the crash you experience is specific to reKonq ; so please open a separate ticket against reKonq.

@roger: 
Do you still have this problem with the most recent release of KDE, v4.7.3 ? If you do, what version of flash did you install and attempt to use ? Also, if you removed the flashplayer properly, then there is no reason why your system should crash afterwards.
Comment 3 Roger Pixley 2011-11-22 16:59:43 UTC 
Hello Dawit. I've never had flash installed and the crashes have stopped since KDE 4.7.3. Back to normal rekonq crashes. Switching Konqueror to khtml fixed the crashes from before that release so I was able to get along.

Thanks for the update. Since the actual crash was in the upstream code (QtWebKit), I am going to close this bug report as upstream. If the crash reoccurs, feel free to reopen this ticket.
