Thank you very much for testing and verifying it again.  Can you please tell me how you did it?  If you could copy and paste the ssldebug.txt file, that will also be very helpful.
 
    Regards,
 
Vijay

I use linux and I just verified it again using the example and the
instructions on http://wiki.wireshark.org/SSL
and once I set the preference properly and I restart wireshark it does
decrypt the example capture just fine.
