Comment(by mdean):

 Looks like playbackbox.cpp (around line 1195) is calling
 MythUIButtonList::GetItemAt() and passing an arg of -1, which results in
 calling QList::at() with an arg of -1, which triggers a Qt abort due to a
 failed assert.  Robert McNamara has a little patch that checks the bounds
 in GetItemAt(), but since the code generally doesn't check validity of the
 value returned by GetItemAt(), we'd need to modify every location where
 GetItemAt() is called.  And, even then, we probably still need to fix the
 issue of calling GetItemAt() with an invalid value.  I'll leave it to the
 MythUI experts to decide what the best approach is--just thought I'd
 mention this in case it saves someone else 30 seconds of digging.  :)
