Description of problem:
I received a phone call from another contact. Pidgin displayed a "$NAME is calling you" window with an option to accept or cancel. I could not choose an option as Pidgin crashed about one second later without any user input.

Version-Release number of selected component:
pidgin-2.10.9-1.fc20
