Description Rui Matos 2015-10-26 09:55:19 UTC

When unplugging monitors, mutter emits this:

Oct 26 10:49:26 dhcp-4-136.brq.redhat.com gnome-session[1953]: (gnome-shell:3073): mutter-CRITICAL **: meta_screen_get_monitor_geometry: assertion 'monitor >= 0 && monitor < screen->n_monitor_infos' failed


This is due to the desktop window (i.e. the nautilus window containing desktop icons in the classic session) being special cased when moving windows due to the monitor unplugging. The special case is required but it's implemented incorrectly, leaving that window associated with invalid monitor data.

This might be a cause for crashes later on, though I didn't actually hit a crash because of it.
