Quassel IRC

Application: quasselclient (v0.7.3 (dist-7db97a6))
KDE Platform Version: 4.7.97 (4.8 RC2 (4.7.97) (Compiled from sources)
Qt Version: 4.7.4
Operating System: Linux 3.1.6-gentoo x86_64
Distribution: "Gentoo Base System release 2.0.3"

-- Information about the crash:
Someone posted the URL http://odbl.poole.ch/germany-20111208-20120111-poly.html in an IRC channel which loads a very huge page containing OpenStreetMap statistics.

I hovered the link and saw the preview for some seconds, before I continued to move the cursor.

Around 5 seconds later, QuasselClient crashed.

The crash can be reproduced every time.

-- Backtrace:
