Bug#932892: libwayland-server0: wayland crashes when I (un)plug a monitor

[Rémi Letot <hobbes@poukram.net>]

Package: libwayland-server0
Version: 1.17.0-1
Severity: normal

Dear Maintainer,

when I plug or unplug a monitor, my desktop session crashes 
and I'm back at the gdm login screen. If I do the same when
at the gdm login screen, it disappears and doesn't come back. 
Then I have to restart the pc.

I have errors in syslog:

gnome-shell[4078]: segfault at ?? ip ???????? sp ???????? error 4 in libwayland-server.so.0.1.0[?????????+7000]

I have several errors since I tried multiple combinations, 
so I replaced the non constant parts of the error with ??.

There are probably things that I can do to have better error
messages, but you'll have to guide me :-)

I'm now using gnome on Xorg, which doesn't crash, so the 
problem is with wayland.

Thanks a lot,
-- 
Rémi
