I believe the fixes do come from the avenard repo on this machine.
deb http://www.avenard.org/files/ubuntu-repos lucid release
I see a new batch of updates - I will upgrade with those and retest.
Thanks for all your work Jean-Yves, I've used your repos for a few years
now (& I still appreciate your VDPAU work with 0.23!)
Thanks, Brian for the other suggestion as well. I understand that
stack trace is something that's generated by using gdb. Here are the
results of my ghb effort. I didn't recompile mythcommflag with
debugging support...but I will if it's necessary (& if I can get a clue
as to how). Here's the gdb bt:
$ gdb bt mythcommflag -c 1391 -s 20101216220000
Excess command line arguments ignored. (mythcommflag)
