Impossible to format a USB who contains bootable ISO

[Hangman]

When you try to format a bootable USB you have the following error :

This partition cannot be modified because it contains a partition table; please reinitialize layout of the whole device. (udisks-error-quark, 11)

and it's impossible to format.

I think it's related to this bug : https://bugs.freedesktop.org/show_bug.cgi?id=76178

Here another bug details and temporary solution : http://askubuntu.com/questions/758219/how-can-i-delete-all-partion-of-my-pen-drive-and-create-a-single-volume

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

Status changed to 'Confirmed' because the bug affects multiple users.

The problem can be avoided by using gparted to format the usb drive
