Compiling with --compile-type=release or --compile-type=debug does not make any difference, it still crashes.

I have noticed that mythtv-setup is only crashing when run on a multicore system. If i limit it to only run on one cpu using "taskset -c 0 mythtv-setup" it runs just fine(!)

The channel scanner in trunk will be replaced with the one from the channel scan branch so trying to fix this isn't a good way to spend our time.
