I installed MultiSystem so I could create a toolkit USB drive, as I have done on previous Xubuntu and Lubuntu machines, following http://www.pendrivelinux.com/multiboot-create-a-multiboot-usb-from-linux/ .
However, doesn't seem to work with Mint Cinnamon 17.1 (and, later, 17.2) as on the first attempt to select the USB drive (pic #5 from the web page cited above), I see this error dialog:
The terminal (VteTerminal) widget requires a version of gtkdialog built with libvte.
Closing that dialog box closes the app.
Where could I go from here? Don't know how to fix.
