Evolution slow when switching mails [delayed formatting]

Binary package hint: evolution

This is a recent regression in Lucid.
Since the last evolution update. Every time i select a new message there is a considerable delay to open new mail [nearly 1sec, seems small delay but it is noticeable only since the last update. ]

Everytime i select a new mail it displays "formatting message..." , I notice a spike in evolution CPU usage and then the message gets displayed. Most importantly this is with plain text messages which i dont think deserve the delays. [I use evolution only for LP mail and mailing lists]
