I have been encountering the same problem and I have no idea why that is.
Especially, I don't understand why cloning should be involved when drawin=
g a=20
double bond. Maybe this is due to redo/undo, but the stacktrace doesn't r=
eally=20
say something about the origin of the error.

Cheers,

Christoph.
