patch and test case

I accidentally called Gtk2::Gdk::GC->new_with_values() with a string instead of a hashref and got some glib warnings and segv.  I think the GdkGCValuesMask passed down to gdk_gc_new_with_values() in that case ends up uninitialized garbage.  It'd be good to avoid trouble by at least zeroing out in that case, per attached.  Unless an error for a non-hashref arg would be better.

I think croak()-ing would indeed be better than silently accepting garbage.  Can you write a patch for that?
Comment 2 GNOME Infrastructure Team 2021-07-05 12:22:33 UTC 
GNOME is going to shut down bugzilla.gnome.org in favor of gitlab.gnome.org.
As part of that, we are mass-closing older open tickets in bugzilla.gnome.org
which have not seen updates for a longer time (resources are unfortunately
quite limited so not every ticket can get handled).

If you can still reproduce the situation described in this ticket in a recent
and supported software version, then please follow
  https://wiki.gnome.org/GettingInTouch/BugReportingGuidelines
and create a new ticket at
  https://gitlab.gnome.org/GNOME?utf8=%E2%9C%93&filter=perl-

Thank you for your understanding and your help.
