DiskSpace applet crashes when mount point is changed

On Mageia-1, w/screenlets-0.1.6, changing the mount point gen's the following when the applet is started/restarted:

Loading instances from cache

This happens whenever /home/username/.config/screenlets/DiskSpace/default/ contains a mount point configuration other than the default one.
