Natural and accidental displayed together

[sertansenturk]

When the accidental of a note symbol changes to another accidental, the natural is printed together with the natural "accidental". It only seems to happen from certain accidentals to another.

I suspect this is a lilypond bug, but I don't have the time to trace the real issue now. Below, I have made a basic example to some examples. @hsercanatli can you try to reproduce it for all note combinations and try to figure out the reason?

If it's related to our package or if we can introduce a temporary fix, we should correct it here. In addition, if it's a LilyPind related bug, we should report it: http://lilypond.org/bug-reports.html
