Comment 7 for bug 1623763

It appears this is actually because glib2.0 is not compiled with --enable-debug so I'm reassigning this to glib2.0 and lowering the importance to wishlist as a new "feature".

I'm also attaching an ancient Debian bug asking for this compile option. Someone that cares about this feature should look into what the impact is of --enable-debug and have a conversation with the Debian maintainers about it.
