Comment 1

[David Baron :dbaron: (⌚️UTC-4, no longer working on Mozilla)]

This bug was observed only on one or more of the six machines listed in
bug 787281 comment 11, which seem likely to have bad memory, disk, or
other hardware problem, based on the rate of failures on those machines
and the types of failures observed.

Therefore I'm marking this bug invalid, though it should be reopened if
it occurs on other (more reliable) hardware.
