GParted segfaults if scrolling quickly in the device dropdown
This was reported as Debian bug 991998 "gparted segfaults if scrolling quickly the device dropdown list".
Move the pointer over the device dropdown list and scroll the mouse wheel quickly up and down. GParted crashes.
I think it requires at least 3 devices in the dropdown to trigger the crash, and having a few more makes it easier to trigger the crash.
GParted 0.23.0 and later crashes. GParted 0.22.0 and earlier doesn't.
