Bastien, could you try the same operation with a previous gparted
version?

I would like to ask Curtis for comments. I hope you can follow the
log in French at the end of this message.

I looked at gparted's source code. Seems like it didn't get partition's
UUID when calling blkid.
When I used lenny's gparted, my swap got an(other ?) UUID, and blkid
returns it. So the newest gparted now works when I want to resize/move
my swap partition.
gparted should look if the UUID is empty in order not to use -U option
with mkswap.

I tried the following command with no problems parsing the empty UUID
string.
$ sudo mkswap -L "" -U "" /dev/sdd3
Setting up swapspace version 1, size = 57569 kB
LABEL=, UUID=f8b00408-e87e-bcbf-7c8b-0408a42eedb7
$
$ mkswap --version
mkswap (util-linux-ng 2.13.1)
$

It seems strange that no UUID was found for your swap partition. Still
it would be more graceful for GParted to continue with the operation
than to fail with a UUID parsing error.
I have implemented your suggestion of only using the mkswap "-U" flag if
the UUID is non-blank.
