gparted/hal permission puzzle

[Stefano Sabatini <stefano.sabatini-lala@poste.it>]

Hi to all debian users,
this is my first post on this list.

I'm having this problem with gparted (Debian lenny):
I launch it with:
sudo gparted 

then I can see:
sds@santefisi ~> ps -e -o user,uid,euid,cmd | grep g[p]arted
root         0     0 gparted


but I get a window with this message just at gparted startup:

Cannot mount volume.
Error org.freedesktop.Hal.Device.PermissionDeniedByPolicy.
Details ->
ha-storage-fixed-mount refused uid 1000
1000 is the uid of my account.

then I can't perform resize operations on the various partitions.

Any hint?

Thanks in advance.
