[Evolution] Very, very slow composition action

[Abel Marrero Santos <marrero uh cu>]

I've started to use evolution recently and i've a noted that when i try
to compose a new message, evolution hangs for aproximately 20 seconds
until the composition windows appears. I don't know if this is the
correct behaviour but I'm very disappointed with it. I have a Pentium IV
at 2GHz, 1Gb RAM. 
I this is a bug I appreciate any notification.

Thanks in advance,
Abel.
