I ended up getting a new motherboard/cpu combo and didn't have the issues there, so I never could quite figure out what was going on. Said hardware is running fine with .27 now.

A few weeks ago I upgraded to 12.04 and also updated MythTV from .25 to .26. Mythwelcome would crash on start about half the time, and I got a lot of crashes for the background processes like mythshutdown and mythpreviewgen. I decided to install from scratch, though I kept /home as is. The crashes are less frequent now. Mythwelcome/Mythfrotend start and operate normally for the most part. I still occasionally get crash reports for mythshutdown and mythpreviewgen, but I can't get them to fail when run manually, so I've been having a hard time getting proper debug information with gdb. Given that I went from no problems to problems instantly after the upgrade, I don't think it is hardware failure, though it could be something buggy that just wasn't exposed before. Mostly I'm just not sure what to look at next. Any ideas? What other information can I gather? This is the only really weird thing I see in the logs, but I haven't been able to figure out if/what kind of problem it is.
