Application: kaffeine (1.2.2)
KDE Platform Version: 4.11.5
Qt Version: 4.8.4
Operating System: Linux 3.11.0-19-generic x86_64
Distribution: Ubuntu 13.10

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

sudo modprobe -rv cx88_blackbird
sudo modprobe -rv cx88-dvb
sudo modprobe -rv cx8800
sudo modprobe -v cx88-dvb

This is run by cron every nigtht at 3 a.m.. Kaffeine crashes a few seconds later every night. Using Ubuntu 13.10 with brand new 5500 card. Never happened with 3000 card.

The crash can be reproduced every time.

-- Backtrace:
