Bug 303758

Application: akregator (1.6.6)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.2.0-3-amd64 x86_64
Distribution: Debian GNU/Linux testing (wheezy)

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

I had just resumed the laptop from sleep mode so I presume that displays were being refreshed etc.  Akregator spontaneously crashed (I had been viewing some pages last night which probably had embedded Flash objects).

#267526 suggests that this crash was an upstream issue fixed in QtWebkit 2.1, however I have QtWebkit 2.2 so perhaps it is still outstanding ?

-- Backtrace:
Application: Akregator (akregator), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
