Looking at the back trace, all the calls are occurring far below MythTV 
code--specifically in Qt's X support code.  But, as the glibc 
"abbreviated" backtrace said, it's in a call for memory allocation, 
requested by libxi (XInput support).

I'd guess (but this isn't much more than a guess) that the problem is 
either with your X (and/or libxi) or is potentially caused by the X 
configuration (and X doesn't handle/protect against the invalid config).
