[Bug 1303276] [NEW] gpgv crashed with SIGSEGV in __GI___libc_malloc()

[Mark Bennison]

Public bug reported:

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.
