Hi, this commit:

http://git.gnome.org/browse/gtk+/commit/gtk/gtkgrid.c?id=d717a2dcfc8603561f8a0f78982244e8b8fd9006

fixed GTK+ to interpret GtkGrid spacing properties as documented.
This change has happened in GTK+ 3.1.18.

We've seen a number of modules affected by this, so here is a general
call to action:

If your modules is using GtkGrid, please check your row and column spacings.
