Hello again maintainers,

On closer inspection, this appears to be a problem with devel/glib20, 
and not Thunar, as I am now seeing Firefox and Thunderbird crashing with 
the same error message.

I have submitted a problem report on the bug tracker for glib:
     https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=199872

Thank you, :-)
