We have a UI regression due to xulrunner changes. Tomeu has done the hard work of finding the right patch to backport, but we need some help on the Fedora side :-) https://bugzilla.redhat.com/show_bug.cgi?id=524377
This affects us here - http://dev.sugarlabs.org/ticket/851
For example - dev.sugarlabs.org and dev.laptop.org are very confusing to use without the missing spinner...
cheers,
