Quicklists not working since upgrade to Ubuntu 15.10

[macho]

Three parts to this report, plus a copy-paste of some error data.

1) I bought a new laptop and upgraded a few Ubuntu versions to 15.10. I installed ubuntu-tweak 0.8.7. I then tried to manually re-insert my Quicklist entries, which is the sole feature of tweaks that I use. I can enter quicklist entries as expected, but they do not seem to have any effect.

2) Ubuntu-tweaks doesn't seem to want to launch from the Unity Taskbar, but starts fine from a terminal, which I guess is nice in a way, because it made me realize there's a bunch of Quicklist error text being generated [see copy-paste below], but is probably not ideal in the long run

3) An extra question that probably doesn't belong in this bug report, sorry: Is there a way for me to migrate my Ubuntu Tweak preferences to my new laptop, so that I don't have to manually recreate them all?

Thanks.
