Description darkxst 2015-03-25 21:44:27 UTC 
After some time media keys stop responding, and can only be restored by restarting both g-s-d and gnome-shell. Not sure if there is a specific trigger or if its just happening after some timeout.

I've not been able to find any useful output in either g-s-d or gnome-session logs.

Comment 1 Marius Gedminas 2015-04-24 08:20:08 UTC 
It looks like this is triggered by VT switches.

journalctl -f shows this when I switch to a text console and back:


(gnome-settings-daemon:10125): GLib-GObject-WARNING **: cannot register existing type 'GsdDevice'
(gnome-settings-daemon:10125): GLib-GObject-WARNING **: cannot add private field to invalid (non-instantiatable) type '<invalid>'
(gnome-settings-daemon:10125): GLib-CRITICAL **: g_once_init_leave: assertion 'result != 0' failed
(gnome-settings-daemon:10125): common-plugin-CRITICAL **: gsd_device_get_device_type: assertion 'GSD_IS_DEVICE (device)' failed


(I stripped the common prefix of these lines, which was "Bal 24 11:03:36 platonas gnome-session[2521]: ")

I can't reproduce this here. Can you attach to g-s-d with gdb, set a breakpoint at write_string and get a stack trace when you get this message?
