Bug Description

(partly taken from the Debian report for this issue)

python-twisted-calendarserver implements a patched version of python-twisted-web2 and python-twisted-runner especially for calendarserver. These conflict with the standard python-twisted. Basically you're putting a customised version of twisted
in the place where the standard twisted should be.

The conflicts that are set prevent anything bad from happening with standard debian/ubuntu packages, but it makes it impossible to run calendarserver on the same machine as any other package that needs twisted.

I can confirm this one, when I tried to install calendarserver I got:

whoops, misread the package name, this seems a conflict with a different package (https://bugs.launchpad.net/ubuntu/+source/twisted-calendarserver/+bug/349837)

This seems to be related to #410098 -- twisted installs a directory named "plugins" but it isn't a Python package, it is just a directory. Some other tools seem to create an __init__.py file and put it into this directory sometimes, and that seems to cause a problem. Or maybe I got it all backwards. Anyway, something is messed up with regard to files named "twisted/plugins/__init__.py" in Debian and Ubuntu.
