Application: konqueror (4.12.5)
KDE Platform Version: 4.12.5
Qt Version: 4.8.6
Operating System: Linux 3.14.7-200.fc20.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
I was watching https://jdh8.github.io/histology-2014/sozi.svg
It is hosted on GitHub, with source available at https://github.com/jdh8/histology-2014

Konqueror crashes even if I load my presentation locally.
This crash only repeats if I choose KHTML as renderer. Webkit does not crash.

The crash can be reproduced every time.

-- Backtrace:
