Nothing happens.

Mmm, not really, but i did try it and i think i have some NFS stuff
running. I stopped nfs-common nfs-kernel-server, but to no avail.
Anyway, i have those running, but no exported filesystems, so ...

Nope, nothing here.

But i have some new datapoint. If i open a .pdf document in nautilus
self (no external app used, well no external window anyway, i guess gpdf
is used), i can umount without problem, but if i use gimp (1.3 i think)
then the problem happens. Will try with other external apps next time.
