Title:
  gpgv crashed with SIGSEGV in __GI___libc_malloc()

Status in “gnupg” package in Ubuntu:
  New

Bug description:
  The computer was idling and the screen was off - I had perhaps been
  away for 20 to 30 minutes. On unlock of the screen I saw the error
  message (probably not as a result of unlocking the screen). Only thing
  running was Chrome.

  I had also just updated the latest patches etc for the 64bit 14.04
  release. Perhaps this is relevant.
