Bug ID: 303758
Severity: crash
Version: 1.6.6
Priority: NOR
Assignee: kdepim-bugs at kde.org
Summary: Flashplayer related crash still happens in QtWebkit
2.2
Classification: Unclassified
OS: Linux
Reporter: nick at leverton.org
Hardware: Debian testing
Status: UNCONFIRMED
Component: general
Product: akregator
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".
