[mythtv-users] Mythmusic seg fault

[Matthew Laird]

Upon digging deeper it seems the call which causes the segfault is line
174 of mythmusic/mythmusic/playbackbox.cpp, at call to updateForeground();

Now not knowing anything about how QT or the Myth GUI work I can't tell if
this seg fault is related to the failed "connect" calls listed below.  Any
suggestions on a remedy would be appriciated.  Thanks again.
