evolution causes al lot of uw-imapd disk activitiy

[Juergen Lueters]

I am using evoluton (1.4), uw-imapd on debian unstable. Evolution and 
uw-imapd are running on the same system.
Evolution and uw-imapd are causing a _lot_ of disk traffic, which makes 
the system almost unusable
for  minutes. Mozilla mail does not show any problem.

Has anybody else seen this problem?
