Title:
  mythfrontend.real crashed with SIGSEGV in QMutex::lock()

Status in MythTV:
  Confirmed
Status in “mythtv” package in Ubuntu:
  Triaged

Bug description:
  Binary package hint: mythtv

  I wanted to quit because I was wrong to select the language and this
  error has occurred.

  I was wrong to select the language because the mouse cursor was not
  visible.
