I can reproduce the issue by unplugging and usb stick! When I plug it in nothing special happens, but when I unplug it the bug appears immediately. The same workaroud (switching VTs) resolves it temporarily.
It does not happen 100% of the time though. It did happen 4 times in a row a few minutes ago. I don't see anything unusual in the log. Here is what I got when unplugging, the first time it triggered the bug: Mar 2 13:48:02 tadzim3 kernel: [48565.861661] usb 2-2: USB disconnect, device number 15 Mar 2 13:48:02 tadzim3 upowerd[2322]: unhandled action 'unbind' on /sys/devices/pci0000:00/0000:00:14.0/usb2/2-2/2-2:1.0 Mar 2 13:48:02 tadzim3 upowerd[2322]: unhandled action 'unbind' on /sys/devices/pci0000:00/0000:00:14.0/usb2/2-2 Mar 2 13:48:02 tadzim3 dbus-daemon[1112]: [system] Activating via systemd: service name='org.freedesktop.hostname1' unit='dbus-org.freedesktop.hostname1.service' requested by ':1.1503' (uid=1000 pid=3197 comm="/usr/bin/gnome-shell " label="unconfined") Mar 2 13:48:02 tadzim3 systemd[1]: Starting Hostname Service...
