Upstream patch to be included in 2.6.6 none

Description Tomas Hoger 2010-02-16 10:12:32 UTC 
Pidgin 2.6.6 is fixing a denial of service (remotely-triggered high CPU use) triggered by large amount of "smileys" in received instant messages.  This issue is addressed by setting a limit on number of smileys processed.
