** Description changed:

- Binary package hint: pidgin
+ 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+ certs/Microsoft_Secure_Server_Authority.pem is outdated.
  
- Hello. It seems that microsoft did some changes
+ 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.
