Dear sadashiva reddy,

You have asked the very smae question before. Reposting such questions again and again is not considered a clever idea. Please see http://catb.org/esr/faqs/smart-questions.html

In the first step I recommend to update to the latest version (top of tree), and try again. If it still doesn't work, then try older versions. If you find a workign one, run git bisect and find out which commit broke it.
Best regards,
