FYI - got the same trap on gnome-shell. > [14336.550781] traps: gnome-shell[46866] trap int3 ip:7f8b0cec135f sp:7ffc99471880 error:0 in libglib-2.0.so.0.6800.1[7f8b0ce85000+8a000] eventually downgrading gsd to =gnome-base/gnome-settings-daemon-3.38.1 cured it.
Yes, same for me.
this is also discussed in bug #786540 - as Sam linked to
(In reply to Christian Bricart from comment #4) > this is also discussed in bug #786540 - as Sam linked to sorry - wrong paste buffer.. bug #786573 ..
$URL looks relevant, but the fixing commits are in the x11-libs/gtk+ and gui-libs/gtk versions in tree, so I don't think it's directly relevant.
