I also get a very similar backtraces if I kill Nautilus but mine looks
more useful (see at the end), as it even has the timeout=25000.
Looks like I have been for two years stumbling in this very bug but just
shrugging it off as it happens only in specific circumstances. To
reproduce the bug consistently:
(1-2 is unnecessary if you already log in to Ubuntu Gnome)
1. systemctl start sddm (any login manager should work I reckon).
2. login to Ubuntu.
3. logout from Ubuntu.
4. systemctl stop sddm.
5. startx /bin/dwm (or mwm, or icewm, ..., I reckon it will work with any
unpretentious window manager).
6. start the Gnome application
Looks like something dbus is left off running as a result of 3/4 and
