That's interesting.

So the code that executes after prompt-for returned NULL was never
tested. So I guess making GTK's prompt-for return NULL will just
introduce more bugs.

Or would the right way be to remove the cancel button from GTK's dialog?
IMHO it's nice to have a possibility to cancel an action.
