Hi Jan,
As a long time follower of this bug, I would like to also point out:
https://bugzilla.redhat.com/show_bug.cgi?id=1490351
Which is related, some (most?) of the gjs crashes (bringing
gnome-shell down) have been resolved for me with 1.48.7, but
F27 is missing the fixes for this. Given that the old systray
compat stuff is gone and we now officially advice TopIcon for
people who need systray icons, I believe we really MUST fix
the gjs fixes missing from F27 before F27 final.
fixes it for you? It's an update to latest gjs 1.50.0 together with new
mozjs52.
