After thinking about things I tried uninstalling Mercurial and TortoiseHg, changing the repositories back to original and reinstalling the original versions and everything was working including the Workbench. So it seems that a key part of the problem for me was the missing .tortoisehg/notify file, Nautilus fails to load the extensions if this is missing.
So I now have the original TortoiseHg working on my system but I'm not certain which actions resulting in the fix. Perhaps if the package maintainers can change the ./tortoise/notify directory to a ./tortoisehg/notify file this will fix the problem. It may however also need some or all of steps 1 to 3 from Olivier's solution to fix the problem. BTW thanks to Olivier for his solution. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/990527 Title: Nautilus Integration Doesn't Work in 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/tortoisehg/+bug/990527/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
