I've seen several of these tickets, but I can't reproduce the crashing
on my system (either because I'm running Master instead of 0.24, or
more likely because of some difference on my system). If you can
reproduce the crash reliably, could you try running valgrind on it?
valgrind --leak-check=yes mythfrontend ...
If there is some kind of memory corruption going on, valgrind might
find something interesting before the crash.
