[mythtv-users] Re: widespread reports of (sort of) the same failures

Well, I managed to get an strace... but no gdb output. It says no
debugging symbols found, even though I'm 100% sure I recompiled and
reinstalled with the debug flag in settings.pro - I even erased the
whole tree and then started over, editing settings.pro by hand just to
be sure.

Here's an strace, and from my (meager) debugging skills, I think it's
a mysql problem. I'm running version 4.1.11.
