A bug Report

When I was translating "Ex: 63aa7f" to Farsi (Persian), KBabel crashed!
This was repeated.
I type:
مثال:63aa
and when my finger goes to button 7 and press it, KBabel crashes!

There is some little problems with farsi, and I guess with right2left 
languages, too. For example some points that are highlighting spaces are 
left2right!

Best Regards,
Reza.
