Title:
  mythfrontend.real crashed with SIGSEGV in QBuffer::buffer()

Status in Mythbuntu:
  New

Bug description:
  Similar to expired bug #1017632 but this is Mythbuntu 14.04 with
  mythtv version 0.27.

  Occurred when slow internet connectivity speed caused Mythweather to
  stop responding; pressing 'Esc' button did not respond either for
  about a minute or two.

  If slow internet connectivity is present, I expect Mythweather to
  allow me to return to the previous menu without hanging the system.
