All I get is:

So I dont know what to do. I know from printf() debug that this
happens on the line:
gtk_widget_show_all(window);

The GRuntimes are caused in the line:
ev = gtk_type_new(gevas_get_type()); // this line errs.

but I can't tell the diffs of my gevas_get_type() and the 
get_type function in some of the code from 1.3.5. so
I will find that one a little later on.
