Thanks for patch, released as: http://git.eclipse.org/c/platform/eclipse.platform.ui.git/commit/?id=ec9d3551cbf269046f41b6f9123f5366be5d7207 Daniel
Verfied in I20140528-2000. "Appearance" page opens correctly, but I get NPE when opening "Colors and Fonts" page. I will open a new bug for this issue.
For the NPE when opening "Colors and Fonts" page I opened bug 436247.
