Bug 265594

Application: kontact (4.4.9)
KDE Platform Version: 4.6.00 (4.6.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.36-bugs i686
Distribution: Ubuntu 10.10

-- Information about the crash:
Every time I try to open Akkregator from within Kontact, Kontact crashes with a segfault. The behaviour is reproducible. This has been happening since the upgrade to KDE SC 4.6.0 - since then Kontact has also been running very slowly/slaggish after start-up for a short period, which then stops and everything seems to be back to normal.

- Custom settings of the application:
None I could think of. There are a lot of feeds in there, some of which might not work any more. Other than that, Akkregator runs with pretty much all the standard settings.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
