Application: konqueror (4.8.4 (4.8.4))
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.8.1 x86_64
Distribution: Debian GNU/Linux 7.0 (wheezy)

-- Information about the crash:
Experienced this with 4.10.1.   I opened the blog link http://blog.martin-graesslin.com/blog/2013/03/an-update-on-kwin-on-5/ seen in another blogroll.  Konqueror spent a few seconds loading and refreshing (didn't catch the refresh URL) then crashed.  Twice (this dump is from the second occasion).

The crash can be reproduced every time.

-- Backtrace:
Application: Konqueror (kdeinit4), signal: Segmentation fault
