Subject: MythTV segmentation faults
I've had a lot of problems since upgrading my MythTV machine to Wheezy.
After installing the latest MythTV packages (as of about a week ago) I
had constant segmentation faults -- almost every time it tried to
record something. I downgraded to 0.26.1-dmo1 and MythTV is working
now, except it doesn't detect commercials.


Here's what I'm getting in mythcommflag.log:

Here's what I was getting in mythbackend.log with the newer version
of MythTV:

Any ideas of what the problem is? This is an i386 machine, in case it matters.
