Crash report filed

It seems to be happening somewhere in the scheduler, log statements lead me to believe it's in FillRecordingDir?.

Is happening with the Ubuntu 12.04.1 and the latest 0.26-fixes branch.

I've figured out more details. It seems post reboot, my HD-PVR got reassigned to /dev/video0 where it used to be /dev/video1. /dev/video1 is now my pcHDTV HD5000 cx8800 which I don't use. Once I switched the encoder back to the correct video device, the server starts up correctly again.

In 0a639d9bdf6612fdf827b123cd2a2f23d0600156/mythtv:

Do not use QMap::operator[] unless map definitely contains the key

QMap::operator[] would add here a NULL entry in the list of cards which would later cause a null dereference.

Fixes #11279
