dosfslabel stops with "Seek to 12345678: invalid argument" on FAT32 volumes

[Andreas Heinlein]

Binary package hint: dosfstools

dosfslabel stops with the error: "Seek to 12345678: invalid argument" (numbers vary, even among several attempts on the same device).

Bug has already been reported and fixed in Fedora (https://bugzilla.redhat.com/show_bug.cgi?id=693662), but obviously not upstream. Bug is also present in Debian up to experimental. The patch attached to above report works for me on natty (dosfstools-3.0.9), but not on lucid (dosfstools-3.0.7).

I have converted the patch to a dpatch and attached it.

Please send this one upstream (again) and to debian as well.

It seems to be broken for a while on FAT32. Cloned to all Fedoras and sent patch upstream.

Reproducer:
# dd if=/dev/zero of=/tmp/img bs=512 count=200k
# mkdosfs -F 32 /tmp/img
# dosfslabel /tmp/img test
