[Bug 1329288] Re: fsck SEGV

[John Lenton]

I'm afraid I was running fsck by hand, and I copied that from the
terminal before moving on to further fsck runs (that didn't explode
like that; I've now got what seems to be all of the data from the disk
in lost+found, dredging through that to see if the backups I don't
have elsewhere are still there).

This was on an ext4 partition that had gotten mangled by an
interrupted gparted run (running gparted over USB turns out to not be
that good an idea).

No logs other than that.
