Bug 272244

Application: rekonq (0.7.0)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-4.dmz.1-liquorix-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

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

I opened an address http://blog.cihar.com/archives/2011/05/02/ppa-debian/

It doesn't happen when I comment the following line in rekonqrc: 
standardFontFamily=

The crash can be reproduced every time.

-- Backtrace:
Application: rekonq (rekonq), signal: Segmentation fault
