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.
