Another error in communication on my part. I performed a clean install 
of Zenwalk 2.2.

I tried inserting the default GET_PROPERTY into the modules that use 
Glib::Object::Subclass and I got further. Some objects were displayed on 
the canvas, but I'm now getting:

*** unhandled exception in callback:
*** Can't locate object method "get_default_value" via package 
"Glib::Param::Boxed" at ../lib/Gtk2/Ex/MindMapView/Item.pm line 227.
*** ignoring at example4.pl line 68.

and also I ran the Glib and Gtk2 regression tests. It looks to me like 
the "f.t" Glib test is confirming that I have problem with 
Glib::Object::Subclass. Maybe you can make more of it. Here's the Glib 
test results:
