I've seen this bug before, but not had the time to chase it up and
reproduce it.

Do you have a design which reproduces the behaviour reliably which you can
share with me (or any of the other developers).

If you had a spare moment, perhaps you could have a go at finding a
sequence of steps to reproduce (the simpler the better). From what I
recall, the bug does not happen with all parts, so the key may be finding
one (and a particular rotation, given your notes above) to test with.
