I'm using the gnome packages included with Fedora 27.

gnome-terminal can crash when interacting with the screen by touch.

It seems to happen reliably if I:
bring up a gnome-terminal
touch the gnome-terminal, which brings up the on-screen keyboard
touch the top-right corner (where the power indicator is), which drops down the menu and hides the on-screen keyboard
touch inside the gnome-terminal again, at which point the gnome-terminal will crash.  (the on-screen keyboard will still come up.)

I just tried it, and it looks like it will kill multiple gnome-terminals if there are several up.
