Comment 8 for bug 552419

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.
