Comment 33 for bug 330272

OK, so in theory if you turn on the daily trunk builds rather than the karmic archive builds, you should get more debugging symbols built in. So first thing i'd recommend is visit http://mythbuntu.org/auto-builds and turn those on. Next if mythbackend isn't getting caught by apport, run it through gdb.

Follow the directions here:

You'll probably want to still run mythbackend as the user "mythtv" though, so to become that user, this is the command to do it:

$ sudo su mythtv -c bash
