Title:
  Frontendmythfrontend.real crashed with SIGSEGV in QString::operator<()

Status in Mythbuntu, Ubuntu derivative focused upon MythTV:
  Expired

Bug description:
  h264 IPTV with Network Recorder: Frontend often hangs during channel
  change (getting "Partial Lock", Screen stays black) and is not able to
  record/livetv anymore until restarting backend. Backend itself does
  not crash. Frontend often does NOT crash either and can be exited
  normally. Sometimes has to be killed though. mythfrontend.real crashed
  with SIGSEGV in QString::operator<()
