The error must be initialized to NULL before using it:
GError *er = NULL;
Otherwise the routine thinks that the GError is already set, and
refuses to set it itself.
Generally when you get "-CRITICAL **" errors, it means that gtk+ has
detected a programming error, as opposed to a runtime error. They
should be treated as if the application had crashed.
