Comment(by cpinkham):

 One more thing.  Can you update to SVN head again and run another test
 with an envrionment variable set which will turn off the threaded loads?
 I'd like to see if that gives a different
 trace or if the issue goes away.  I want to see if it's part of the
 threading or part of all the
 other changes I had to make to get the threading working.

 export DISABLETHREADEDMYTHUIIMAGE=1

 (or whatever method your shell uses)
 Then run the normal mythfrontend command with "-v file,extra" under gdb.
 You should not see any
 messages in the log saying mythfrontend spawned a new thread to load
 images, they all shoudld say that the image is being loaded in the
 foreground.

 Please upload a new log and backtrace from this as I think this will aid
 in debugging.
