Bug Description

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu

Ubuntu 14.04

2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center

usb-creator-gtk 0.2.56.3

3) What you expected to happen

1. prepare an isohybrid ISO image, such as the ubuntu ISO:
http://releases.ubuntu.com/14.04.1/ubuntu-14.04-desktop-amd64.iso
2. plug in the usbstick and dd the iso to it
sudo dd if=ubuntu.iso of=/dev/sdb bs=1M
3. eject the usbstick
sudo eject /dev/sdb
4. plug out & in the usbstick
5. launch usb-creator-gtk and erase the usbstick

The usbstick should be erased successfully

4) What happened instead

An error dialog is popped with below messages:

org.freedesktop.DBus.Python.gi._glib.GError: Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/dbus/service.py", line 707, in _message_cb

On ubuntu 14.10 (usb-creator 0.2.62ubuntu0.1, util-linux 2.25.1-3ubuntu4) the error message is:

Fix, by moving the backup to the end (and removing the old backup)?
Warning: Not all of the space available to /dev/sdb appears to be used, you can fix the GPT to use all of the space (an extra 31250608 blocks) or continue with the current setting?
Error: Can't have overlapping partitions.

Workaround is to partition the disk by e.g. gparted to fat32 format. Or maybe just remove existing partitions by it?
