[mythtv-users] frontend crash on start after upgrade to latest svn: memory corruption error

I am running ubuntu edgy on one of my frontends and I upgraded to the latest
svn about two weeks ago and it worked fine. I installed another frontend two
nights ago and had to upgrade my back and frontend because of protocal
mismatch. My backend and the new frontend is working fine. The old frontend
that was working with .20.2 crashes on startup. I submitted a ticket but
haven't seen much yet. There are a lot of changes being made and I'm sure
that's what got me but I thought I would see if anyone else has seen this
problem. Below is the error message

Aborted

I also renamed my theme so it would go back to default to make sure that
isn't it and I also deleted the .mythtv directory since I don't think it is
used anymore. No luck. The full ticket can be referenced
here<http://svn.mythtv.org/trac/ticket/3985>.
Thanks for any help.
