The complete error that is being written thousands of times to my syslog is

Dec 29 07:53:07 localhost org.gnome.Shell.desktop[3120]: (gnome-shell:3120): Clutter-CRITICAL **: clutter_layout_manager_get_child_meta:  assertion 'CLUTTER_IS_LAYOUT_MANAGER (manager)' failed

Because of this my syslog from yesterday at 7:35am until today at 7:35am when it's rotated is - 238121171 Dec 29 07:35 syslog.1 in fact it's so large for some reason it wasn't compressed. Today's syslog so far is 40027866 Dec 29 16:57 syslog and I imagine by tomorrow morning it will be close to the same size as yesterdays.

So, question is what's causing this and how can I troubleshoot and fix it?
