I've played around a little bit. Seems like the client wasn't linked to the dropped account. A Manuel start of ~/.dropbox-dist/dropboxd in a terminal throws an error with a one time link to the dropbox-dist homepage.
After I opened that link in a normal browser my pc was correctly linked to dropbox.
The GUI still doesn't work,but the files are being synchronized by the daemon.
Status reports only via terminal commands...
