Description Gunter Ohrner 2011-10-23 16:53:59 UTC 
Application: rekonq (0.7.90)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

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

Tried to open www.boeblingen.de , but such crashes happen on many sites, especially if the system has moderate to high IO load and thus rekonq is slowed down while rendering the page.

This was the only open tab at the time of the crash.

- Custom settings of the application:

Browser plugins were configured to be loaded "on demand",  I didn't manually enable any plugins on that page before the crash happened.

The crash can be reproduced some of the time.

-- Backtrace:
Application: rekonq (kdeinit4), signal: Aborted

> Browser plugins were configured to be loaded "on demand"

That's odd, because the crash actually happens inside libflashplayer. Maybe you have some exceptions, so that Flash is loaded regardless of the "load on demand" setting.
Comment 2 Jekyll Wu 2012-07-04 01:33:14 UTC 
crash within flashplayer
