Description of problem:
After an insertion of a removable media, like a USB memory key,
it gets mounted and nautilus shows it on a desktop (albeit with
a "generic" icon). There is "Unmount Volume" on an icon menu but
picking it up is totally ineffective. Nothing happens.
OTOH typing in terminal window something like
gnome-mount -u -p /media/disk
does requested unmounting and after that the corresponding icon
disappears from a desktop.
Is this related to bug 328101 by any chance?
Version-Release number of selected component (if applicable):
At this moment it is possible to unmount removable media again.
