Subject: [PATCH 1/1] fix compilation with gcc 6.2.1

Compilation fails with recent versions of gcc with:

error: cannot convert 'Glib::RefPtr<Gdk::Colormap>' to 'bool' in
assignment

and

error: no match for 'operator!=' (operand types are
'Glib::RefPtr<Gdk::Window>' and 'int')

This fixes compilation with gcc 6.2.1.
