It would appear that Pidgin is distributing an intermediate certificate 
for Microsoft Internet Authority than expired in 2011.

This affects all Windows users.  Whether it affects users of other 
operating systems depends on whether:

1) they provide a central store of certificate authority certificates;
2) Pidgin has been built to use that store.

As most of this is on another thread, you should subscribe to the 
support list, or follow it on the archives, for further details.
