Comment (by ari):

 I've gotten a lot of reports about this, and it seems to be related to
 Jabber. Steps to reproduce:

 1) use SSH to create a port forward tunnel for jabber
         eg: -L 5222:some.remote.host:5222 localhost

 2) connect to the remote server via the tunnel (that is, set the jabber
 prefs to connect to localhost:5222)

 3) after the connection is up, exit the SSH connection and fully
 terminate any forwarded ports via ctrl-c, if SSH does not exit on its own

 Immediately thereafter, Pidgin will go into a 100% CPU usage loop.  If one
 restarts the SSH link
 fairly quickly after, Pidgin will return to normal.  However, if a long
 period of time transpires with no connectivity, Pidgin appears to become
 permanently non-responsive. A backtrace of the running process doesn't
 seem to show anything interesting, just the normal gtk event loop:
