OK thanks a lot! I followed the exact same sequence of steps, however still NOT able to decode SSL traffic. So, obviously something is wrong with my local build.
Can you please confirm the version for libgcrypt and gnutls packages on your system? Here is the information from my system:
[vijay@hostname vijay]$ rpmquery -a | grep -i gcrypt
libgcrypt11-1.2.2-12.el3.at
libgcrypt-devel-1.2.2-12.el3.at
[vijay@hostname vijay]$ rpmquery -a | grep -i gnutls
gnutls-1.0.20-4_2.RHL9.at
gnutls-devel-1.0.20-4_2.RHL9.at
[vijay@hlthbnftsprovider vijay]$
Are there any other dependencies that could be effecting my results?
Kind regards,
Vijay

I did this :
Unpacked the example from wiki.wireshark.org/SSL into the current directory.
Started wireshark and set the SSL preference line to :
127.0.0.1,443,http,./rsasnakeoil2.key
applied the change and exited wireshark.
From this directory I then start wireshark again with the command :
wireshark -n -r ./rsasnakeoil2.cap
I click on packet #50 and can see the HTTP GET command that is
transported inside SSL.
This works fine for me on linux.
