I take a look.

Bug 1147435 might fix this bug.

other bug fix landed today; will monitor Last crash reported in socorro : 20150325083046

Last crash I see is still before the other bug : 20150326160206 It's been one week. Going to close this out as a dup for now and will reopen if I see it still occurring.
