[galaxy-dev] "Edit settings" button in Trackster is no longer working (15.10)

Hi all Since we upgraded our Galaxy installation from 15.05 to 15.10 (plus the recent security fix, changeset: 17161:3f95c21b1a85), the "Edit settings" button in Trackster is no longer working. The window, which normally allows you to select the colors, etc. doesn't show up anymore. This happens with different browsers on mac and linux. On the console I get: "TypeError: a.browser is undefined" Has anyone else seen this problem? Or is there even already a fix available?
