[SyncEvolution] local, status 20043

Hi, Everytime there's an dist-upgrade on ubuntu I seem to have problems with syncevolution. This time it seems to work ok until it outputs the following lines: """ [INFO] sync: /org/syncevolution/Session/12397595441382995192: [ERROR] sync: /org/syncevolution/Session/12397595441382995192: error code from SyncEvolution external transport failure (local, status 20043): sync failed """ Any help is welcome! Thanks, Stephan
