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. ** Package changed: gtk+3.0 (Ubuntu) => ubuntu ** Changed in: ubuntu Importance: Low => Wishlist ** Package changed: ubuntu => glib2.0 (Ubuntu) ** Bug watch added: Debian Bug tracker #170726 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=170726 ** Also affects: glib2.0 (Debian) via http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=170726 Importance: Unknown Status: Unknown -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gtk+3.0 in Ubuntu. https://bugs.launchpad.net/bugs/1623763 Title: GTK Inspector Statistics tab non-functional To manage notifications about this bug go to: https://bugs.launchpad.net/gtk/+bug/1623763/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
