Thanks, this bug is now fixed. But there is something wrong with the two diacritics (short vowels): ARABIC KASRA and ARABIC KASRATAN. They should appear UNDER the letters, not IN or OVER them.

Try a-A [Sheen-Kasra] or a-S [Sheen-Kasratan] or d-S [Ya-Kasratan]. 
But h-S or m-S has the correct form. (?)

I tested this trunk:
 emacs-20120903-r109861-bin-i386.zip         03-Sep-2012 03:07   58M  

The arabic letters don't have a constant form. This seems to be the problem (?): Try f-S and compare with f-S-f.
