Bug#987875: atril segfaults in su'ed environment
Package: atril
Version: 1.24.0-1
Severity: normal
X-Debbugs-Cc: schaecsn@gmx.net
atril dereferences a null pointer in ./shell/ev-media-player-keys.c:ev_media_player_keys_focused() when invoked from su - <otheruser>. atril runs fine under the initial user.
To reproduce, su - into another user, may it be root or non-root, export DISPLAY=:0 and run atril without any further arguments.
$ atril
