right-click option "format" launches 2 instances of Nautilus when finished

[Ghislain Vaillant]

To format a USB pendrive, I usually right-click it on the unity bar and select "Format...". This is very handy as it is a user-friendly command to an otherwise more cumbersome manipulation in Disk Utility. However when done, the script tries to launch Nautilus on the newly formated USB pendrive. On my computer, this results to 2 instances of Nautilus being launched instead of a single one. Both of them correctly default to the Pendrive mount point.

Steps to reproduce the bug:
1) Insert the pendrive to format
2) Right-click on its icon appearing in the Unity launch bar
3) Select "Format..."
4) Leave the default options, ie: FAT and New Volume
5) Wait for the script to finish
6) When done, 2 instances of Nautilus gets launched.

Expected results:
- Only one instance should be launched

I am adding this screenshot which shows 2 icons of the "Format..." script in the Unity launch bar, which suggests maybe 2 instances of the Format script are being executed each of them launching Nautilus on completion ?

Marking as invalid on unity trunk because the format menu item has been removed a while ago. Marking as won't fix for 12.04 due to the low priority.
