Bug#498518: bug seems to occur on most linux 2.6 kernels because of corrupt filesystem

[<bugs@nano-net.ro>]

Trying to fix my system I discovered that every linux 2.6 livecd hits the
bug during the command "reiserfsck --rebuild-tree /dev/sda1". The bug also
occured while fsck-ing a corrupt fat32 partition. The same happened after
mounting the damaged fat32 partition and trying to copy some files on a
backup drive. It looks like the bug is caused by filesystem corruption or
because of the partition table corruption (it occurred both when fsck-ing
reiserfs and fat32). I fscked the fat32 partition using a freebsd disk and
it didn't seem to be damaged that bad (only few files were damaged).
