Comment 1 for bug 536670

I just checked that I can reproduce that in the test suite, which uses a clean and zeroed-out device, so it's not the usual "gets confused about two different signatures on the device".

http://cgit.freedesktop.org/udisks/commit/?id=47ac2676ca6d209705f9f814cded2daf19f24e76

Now the test suite properly fails:

$ sudo tests/run FS.test_vfat
Testing binaries from local build tree
daemon path: src/udisks-daemon
mdadm: array /dev/md125 started.
fs: FAT ... [cli]FAIL
