This is an americanism in the CTree widget.  On american keyboards the +
is shifted, on norvegian (and danish) keyboards it is not.  The same
goes for the = (toggle) binding.

The keyboard mapping doesn't matter, but the shift state does.  There
should be a way in gtk to specify a key binding to use if there is no
specific binding for the actual modifier state.

To fix it, take a look at the sources (gtk/gtkctree.c) and find the
bindings that bother you.  Search for "gtk_binding_entry_add_signal" to
find the right spot. Then duplicate the appropriate lines, so there are
bindings for + and = both with and without shift pressed. 

I posted a fix for the CTree widget to http://bugs.gnome.org/ on the
gtk+ wishlish.  I have never heard anything about it, though.  I have no
idea if the maintainers actually read the postings there.
