Description of problem:
I plugged in the USB thumbdrive, then tried to repartition and reformat it.

This error most likely was caused because the drive was currently mounted when I tried to repartition and format it.

After unmounting the drive the partition and format completed successfully.

Version-Release number of selected component:
gparted-0.16.1-2.fc19
