Q:

Rabbit VCS stopped working after upgrade to 11.10

Been using RabbitVCS for months now happily. Then when I updated to Oneric on Monday Rabbit VCS stopped working. 
It is installed but the right click menu in nautilus is gone and unintsalling/reinstalling does nothing. It sees to be available from the command line but the GUI seems to have vanished. 

A:

Update: I've now uploaded the packages to the PPA.
Update: See this mailing list post — there should be a release soon.
I'm the packager for RabbitVCS, and I can confirm that @kikixx is correct — the changes in the Nautilus/Python bindings to v1.0 require a bit of work before the extension is usable in Ubuntu 11.10.
Adam is working on this, but he's not quite there yet (as evinced by the reports of those running the extension out of SVN). Once it's working, we'll have it up in our testing PPA. I honestly don't know how long that'll take though.
