Umounting iPod mini causes error message

[endy]

When right clicking on the desktop icon of my mounted iPod mini and selecting
"Unmount volume" a dialogue box pops up stating "Unable to eject media" with the
following error message "eject: unable to eject, last error: Invalid argument".

However, the iPod does appear to unmount OK, running "df" confirms this. If I
"sudo umount /dev/sdb3" there is no error output to the the console, could this
be a false error dialogue?

The iPod is formatted with the default HFS+ if thats helps, and otherwise seems
fine.

I get the same error when trying to unmount my USB harddisk over the GUI. Since
the iPod seems to be an USB mass storage device, too, I think this is the same
problem.
When I pumount /dev/sda1 in a terminal, I get no error.

I also think, bug #24845 is a duplicate of this. (Not sure about this)

For me this bug first appeared with Breezy, it wasn't there in Hoary.

Martin, do you happen to know what that "Invalid argument" thing is about?

[Martin Pitt (pitti)]

Yes, this is a very well known bug.
