I tested it, and although I didn't actually manage to reproduce the 
visible symptoms at first, stepping through the code revealed some bad 
internal behaviour that could well lead to the phenomenon mentioned.

It turns out that we did have a fencepost error in the code that checks 
whether a rendered block is consecutive to the previous ones or not.

(I also noticed that the respective code is pretty braindead anyway, but 
as it won't lead to errors - to the contrary, there's nothing much to go 
wrong in there except for that one fencepost - I think we can live with 
it for 3.7.0.)


BTW, the bug is now officially FS#270.
