Bug 296396

Application: akregator (4.7.4)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.1.9-1.4-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
Akregator sometimes crashes, especially when opening page containing flash, when opening more pages quickly after each other and so on... I don't see any pattern in it. Sometimes it happens several times during a day, sometimes, there are days withou any single problem...

The crash can be reproduced some of the time.

-- Backtrace:
Application: Akregator (akregator), signal: Segmentation fault
