Sentry Crash Report:

Description H.H. 2012-02-20 18:22:28 UTC 
Application: akregator (4.8.0)
KDE Platform Version: 4.8.00 (4.8.0 "release 1"
Qt Version: 4.8.0
Operating System: Linux 2.6.37.6-0.11-desktop x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
I configured akregator to always load the full HTML page into the article-detail-view. Since kde-4.8 often, when I click a link (which opens in a new akregator tab), akregator crashes.

The crash can be reproduced some of the time.

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