Yep, I just upgraded to trunk today and had a similar issue.  After
running mythfrontend under gdb, I found that it was the MediaMonitor
object that was freaking out.

In particular, it was in mythmediamonitor.cpp:

QString target = getSymlinkTarget(*dev);

The problem was that my DVD device used to symlink /dev/dvd to
/dev/hda.  I upgraded the OS along with my copy of Myth, and the DVD
link was updated to point to /dev/sr0.  My 'settings' table in the
mythconverg database was still set up to look for /dev/hda... which
didn't exist anymore.  This caused the crash.

I removed the offending '/dev/hda' from the 'settings' table, and
voila.  Works great now. :)
