I've asked one of the users reproducing this to test the patch, and he
confirmed that it works fine.  Thanks!

That said, I'd personally avoid the 'SD.__self__' part and just kept
the actual list as a variable.  I'm not 100% sure but I think this could
qualify relying on implementation details, and therefore could break
at some point in the future.
