Comment(by AmigoJack):

 Can confirm this with version 2.7.1 with GTK 2.16.6.0 on Windows XP SP2.

 It is no problem with any plugin. I also got a custom smiley theme
 "Trillian". Having a conversation with animated icons makes the CPU usage
 go high (up to 40% on an Intel Core Duo 6400 @ 2.1 GHz). Selecting all the
 text and disabling all them icons by rightclick immediately calms down the
 CPU. I am pretty sure it's because of animated icons. Can the culprit be
 any GIF implementation? Or GTK itself? If I rightclick on the window title
 to bring up the system menu I can also reduce the CPU load to 0% -
 although the animated smileys still animate as before. This behaviour does
 not make sense - I tend to suspect GTK rather than a GIF implementation.
 It is also no multicore problem - forcing to use only one CPU core or both
 doesn't change anything.

 The protocol being used doesn't matter also - it happens via ICQ and XMPP.

 Does it really help to attach a debug log?
