Commit message

fix bug 620506 by cherrypicking the storm fix for bug 627442.

Description of the change

This branch fixes bug 620506 and bug 627442. These are both caused by underlying bugs in Storm. I brought the pertinent fix back to 0.17, so the new, custom storm release is 0.17 with only the cherrypick of the pertinent fix. The Storm branch includes a test, which passes, and which I am considering to be the test for this branch.

I was able to remove a previous hack around the problem because of this change. Previous tests added at that time continue to pass.

Local QA: https://api.launchpad.dev/beta/~landscape-developers/members?ws.size=1 breaks on devel, and works with this change.

Lint is happy.

This is a release-critical candidate.
