--- Comment #21 from Hime Haieto <himehaieto at gmail dot com> --- Sorry to leave you hanging this long, but I was actually testing this rather extensively since your last update, both for dummy test cases and my real (generic containers) application for it. I've thus far been unable to break it again, so I feel reasonably confident that the latest patch fixed the root cause of the bug.
