Bug Description

Binary package hint: apport

Running ubuntu-bug from the command line I get:

$ ubuntu-bug apport
/usr/lib/pymodules/python2.6/lazr/restfulclient/__init__.py:19: UserWarning: Module launchpadlib was already imported from /usr/lib/pymodules/python2.6/launchpadlib/__init__.py, but /usr/lib/pymodules/python2.6 is being added to sys.path
import pkg_resources

Everything seems to work correctly anyway.

This is affecting many launchpadlib clients - pqm, bzr, apport

apport (Ubuntu) → python-launchpadlib (Ubuntu)

How is this invalid ?

Specifically, this makes bzr and many other scripts ugly; we should only fix this once. If its not a problem with launchpadlib, point us where you think the problem is and we can fix it. However, at the moment, only launchpadlib exhibits this problem, and its a really unpleasant UI wart - we'll want to do an SRU to lucid to fix it up, at minimum.

Because it probably needs to be fixed in the ubuntu package python-launchpadlib.

Some more data: running a script that imports launchpadlib, as root, showed the warning, but fixed it for subsequent runs as a normal user. Hypothesis - something stale, non-rebuilt stuff somewhere and packaging scripts not fixing it. This may mean that most users won't encounter it. It certainly means I don't anymore (and can't reproduce it either). I'm going to look for files it modified though.

The only way in which launchpadlib-the-software is involved is by importing pkg_resources. That's the only line of code from the software that has run when the UserWarning occurs. That's why I believe it to be invalid.

Robert and I talked about this on IRC, and he got the results described above in comments 6 and 7. Pertinent notes, from my perspective, follow.

- Robert said that this is hard to dupe. It was happening consistently on his machines. Other developers did not see, or reported seeing in the past but do not see now.

- I suspect the cause is some combination of the system (post-update, post-delete, or post-addition of some package) + setuptools + our Ubuntu python dances. Robert's mtime search suggests that a launchpadlib upgrade might cause this? It seems unlikely, but there's nothing to contradict it.

If we can dupe, I'm happy to help. I'm not sure what else to do.

I'm not sure either; it seems unlikely to be an explicit action taken by launchpadlib; sigh setuptools. Possibly best to just FAQ-and-close in Ubuntu as well.
