[mythtv] Commercial flagging stopped working for me sometime after rev 9287

I spent several hours last night cleaning everything out and recompiling
and installing, but mythcommflag still crashes for me immediately after
printing "Finding Logo" if i run it manually, and it is apparently
crashing when run by the job queue as well. Here's some gdb output of a
manual run I just did. How do I get Symbol information included? Or is
that not necessary? At this point I'm thinking there's something wrong
with the files themselves, although it crashes on every recording.
I've tried to figure this out on my own to the best of my abilities, but
I'm not really able to follow the code well enough to know where to look
next. Any help would be appreciated.
