FYI, GDebi doesn't seem to let you downgrade packages. I installed 0.9.11-1 and it just plain didn't work. (I get the default GTK engine.) Upgrading to 0.9.12-2 worked, but the tabs are still behaving like they are now. And 0.9.12-3 is the latest version. -- Some tabs missing orange highlight https://launchpad.net/bugs/83840
