gulong gvir_connection_get_version(GVirConnection *conn, GError **error)
would feel more natural here as errors can be reported through the GError.

Same comment as in the previous patch, I'd add a
 g_return_val_if_fail(err == NULL || *err == NULL, 0);

extra space before 'virConnectGetVersion'

Looks good otherwise.
