Sorry for the delay.
I can't reproduce the crash, but instead when trying to unmount the drive it gets stuck at "Searching /dev/sdb partitions". Even after closing the Gparted window, I am left with three processes:
greg@lmh:~$ ps -A | grep gparted 15719 ? 00:00:00 gparted-pkexec 15720 ? 00:00:00 gparted 15769 ? 00:00:03 gpartedbin
This happens with both the repostitory gparted, and with the verson in your ppa.
