Bug 1296411

Description of problem:
In polari I clicked on + button -> chose Enter the room (I use it in check, so names will be just my guesses) -> Wrote '#' to the 'Room name' field. It suggested a previously visited room but after that it immediately crashed.

Version-Release number of selected component:
gjs-1.45.3-1.fc24
