Comment 11 for bug 1241924

Hello,
I had the same problem after upgrading from kubuntu 13.04 to 13.10: Kazam wouldn't record in mp4, it immediately crashed.
I had a little adventure after trying to upgrade my nvidia drivers: It was a disaster, and I had to uninstall them.

From then on, on startup I had always kdaemon crashing and the cause was kscreen and libkscreen.
I uninstalled them and the system was back to normal again. And what's more, Kazam now records mp4 and sound normally.

I hope it helps, I am no programmer but maybe kscreen is connected in some way.
