evolution not loading mails on start

[crhein]

When starting evolution by clicking in application-->internet-->evolution or the button top write evolution hangs on loading my mail acounts.
If I start Evolution with a Terminal it is working almost all the time. If not I have to log out from my session and log in again and load evolution from the Terminal. Then it works again.
