Application: konqueror (4.7.4 (4.7.4))
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.8.0
Operating System: Linux 3.2.0-2-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

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

I opened:

https://bugs.kde.org/buglist.cgi?list_id=21789&query_format=advanced&bug_status=UNCONFIRMED&bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&target_milestone=4.9&product=kwin

in Konqueror.

It does not matter whether I use Webkit or KHTML. The backtrace is with webkit.

In Rekonq 0.9 accessing the webpage works.

I use:

martin@merkaba:~> apt-show-versions | egrep "(konqueror|libqtgui)"
konqueror/sid uptodate 4:4.7.4-2
konqueror-nsplugins/sid uptodate 4:4.7.4-2
konqueror-plugin-gnash/sid uptodate 0.8.10-5
libqtgui4/experimental uptodate 4:4.8.0-1

The crash can be reproduced every time.
