You have good intuition. The problem is with the Icons. My custom theme was using the Tangerine icons; selecting any of the other Icons (Human, Humanity, etc.) results in the correct appearance.
Are the Tangerine icons outdated or no longer supported, or do I need to reinstall from another source? apt-cache policy tangerine-icon-theme tangerine-icon-theme: Installed: 0.27 Candidate: 0.27 Version table: *** 0.27 0 500 http://debian.nctu.edu.tw karmic/universe Packages 100 /var/lib/dpkg/status -- Gnome add to panel > add (custom) Menu Bar | icon size is too big! https://bugs.launchpad.net/bugs/467997 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
