/An Xserver error could happen if something went wrong with setting the 
strut properties.  All X property errors would normally be 'fatal', but 
we don't want this one to be, and in fact can ignore it, so we push/pop 
a Gdk error trap here.

It's common practice to push/pop an error trap around direct Xlib API 
calls like XChangeProperty, inside a gtk+ application.
