Purging chroot-autobuild/build/buildd/opencity-0.0.6.2stable

Nigel: Please close the bug in your changelog entry.
Also one generally uses URLs rather than jsut bug numbers in the DEP3 headers.
And I'm not mad about patches called "fix-ftbfs".

All of the above is pretty nitpicky :)

[Nigel Babu (nigelbabu)]

Thanks for the comments tumbleweed. I'm definitely rusty after a while of not doing this. Attaching a new debdiff which addresses all of what you noted

[Launchpad Janitor (janitor)]
