You have been subscribed to a public bug: Whilst working normally, I was unable to interact with gnome-shell. The clock at the top of the screen continued to increment, and I could ssh in to the machine, but clicking anywhere on the screen resulted in nothing. Changing to another VTY and back again had no effect.
I logged in via ssh, killed gnome-shell and re-ran it using 'DISPLAY=:0.0 gnome-shell' which resolved the problem enough for me to save work and reboot. The following appeared in syslog - the crash was possibly around 1001: Aug 16 10:02:17 angel gnome-shell[2530]: pushModal: invocation of begin_modal failed Aug 16 10:04:45 angel gnome-shell[2530]: g_array_unref: assertion 'array' failed Aug 16 10:04:45 angel gnome-shell[2530]: g_array_unref: assertion 'array' failed Aug 16 10:04:45 angel gnome-shell[2530]: g_array_unref: assertion 'array' failed Aug 16 10:04:45 angel gnome-shell[2530]: g_array_unref: assertion 'array' failed Aug 16 10:04:45 angel gnome-shell[2530]: message repeated 2 times: [ g_array_unref: assertion 'array' failed] Aug 16 10:04:54 angel gnome-shell[2530]: g_array_unref: assertion 'array' failed Aug 16 10:04:54 angel gnome-shell[2530]: g_array_unref: assertion 'array' failed Aug 16 10:05:45 angel gnome-shell[2530]: Object St.Bin (0x55efe0934460), has been already finalized.
