handler, and cannot implement their own log handler, nor can they
seperate out the warnings from the program's intended output.

Suffucient would be some chosable switch in glib that obeys some kind of
env variable like

The GTK developers insisted on interpreting the bug as a request to not
issue warnings.  They did not address the ability to filter the warnings
as a usability issue.
