Sorry the possible beginner question: How can possible I help testing 
this patch under Lucid?
Enough if I downloading actual Lucid awailable Pidgin source and try 
rebuilding the package if I put the patch under debian/patches directory 
and looking few days MSN connection?
I very would like help, because my Maverick system only with my testing 
system and Lucid the normal work system.
My wife using Lucid she's machine too.

Status in Pidgin: New
Status in “pidgin” package in Ubuntu: Fix Released
Status in “pidgin” source package in Maverick: Fix Committed

Bug description:
When attempting to connect to MSN, Pidgin fails to load the contact list, citing an issue with the SSL certificate of omega.contacts.msn.com. This happened due to Microsoft renewing both the omega.contacts.msn.com certificate, as well as their certification authority certificate "Microsoft Secure Server Authority". Hence, the certificate in /usr/share/purple/ca-certs/Microsoft_Secure_Server_Authority.pem is outdated.

In addition, the transition from the old to the new certificate is not complete, only half-done, so a simple workaround of updating the certificate would not work. Both the old and new certificates have to be included. Debdiffs for natty and maverick are attached.

TEST CASE:
1. Start Pidgin
2. Click Tools->Certificates
3. Delete the omega.contacts.msn.com certificate
4. Try connecting to a MSN messenger account
5. If it fails with "Unable to validate certificate", then this bug is present.
