 [Pidgin 2.12.0 on 4.13.9-1-ARCH with Gnome DE running 'gdm' on 'xorg']

 Hello, just as the title says. A buddy of mine apparently started an
 encrypted conversation which now appears as  "!buddy_name"   in my buddy
 list, next to the regular same buddy's "buddy_name" entry.

 I want to remove "!buddy_name". I can't. Everytime I try a confirmation
 window appears. It reads: "Abort Secret Chat: do you want to terminate
 this secret chat permanently?"
 Clicking OK at this point, makes Pidgin dump core.

 $ journalctl -xe | grep pidgin
