can you upload ~/.cache/unity-tweak-tool/debug.log from the machine you saw this crash?
Looks like one of the underlying gsettings keys have been messed with in the 14.10 release. I figured it is on the launcher tab and is a switch control, but that is all the information I get from the traceback. The debug log should atleast identify precisely what caused this crash. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1378016 Title: unity-tweak-tool crashed with KeyError in refresh(): 3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity-tweak-tool/+bug/1378016/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
