"Safely remove" kills SD drive (Maverick, Gnome)

[Thierry de Coulon]

Hi all,

Once again I'm new both to Ubuntu and Gnome (but not to Linux), and I do know 
maverick is still RC, so I'm not criticizing, just asking.

I have this (strange) behaviour:

My Lapotop has an SD slot that is identified as /dev/sdb
My /etc/fstab has  /dev/sdb1 /media/sd  auto   noauto,users,exec,rw 0 0

If I boot with an SD card in the slot, it gets mounted on /media/sd (despite 
the noauto) and an icon appears on the desktop.
If I  right-click on the icon and choose "Safely remove", it umounts, but the 
slot becomes unvailable (if you try to mount or fdisk /dev/sdb, it says it 
does not exist).

However:

I created two scripts that read:

mount /media/sd
umount /media/sd

I created a drawer in the panel and put the scripts there. If I mount and 
umount my SD cards with the scripts, everything works very well (i.e. the SD 
card mounts, an icon appears on the desktop, the sd card umounts, I can mount 
the next one, etc...)

So... can anyone explain to me why the most natural way (safe umounting from 
Gnome) fails, while mounting/umounting from the system itself works. Is this 
some Gnome bug? (sorry, I have no other Gnoome desktop around to test).

I'd think there is some sort of screwed "automounting" tool running amok 
there.

Thierry
