(gnome-shell:2753): Gjs-WARNING **: JS ERROR:

Asked by chris pollock on 2016-10-20

I see the above a lot, the complete line is

Oct 20 14:52:07 localhost gnome-session[2683]: (gnome-shell:2753): Gjs-WARNING **: JS ERROR: Error: Failed to convert UTF-8 string to JS string: Invalid byte sequence in conversion input

I've included my distribution info, version of Gnome Shell and since it mentions a 'container' the version of snapd I'm running just in case.

Question is, what can be the cause of the below syslog output?
