Comment 2 for bug 386203

(I guess it's a rich-root-pack format repo, as the indices aren't in btree (1.9) format.)

Line 451 of that .tix file is pretty obviously corrupted; it's filled with about 5313 bytes of binary garbage of some sort. It seems unlikely that bzr would have written that, so my wild guess would be that there's a hardware or filesystem issue.
