These look like bugs in Windows GTK caused by incompatibilities
introduced in GTK 3.x.
It is certainly so for gtk_widget_get_can_default. This bug is in the
dialog boxes which do not set Can_Default on any of their buttons. God
knows why this is necessary and why this is "critical". GTK dialog boxes
are in general broken, but you can work around of most of the problems.
For others I cannot tell for sure. Add tracing to you program to
identify the place where the error message appear. Then you could figure
out how to deal with that.
Remember, each new version of GTK introduces new bugs and
incompatibilities. You cannot assume that any part of old code would work.
