ubuntuone-client applet can not connect, "Protocol version error" in syncdaemon.log

[vanDrunen]

Binary package hint: ubuntuone-client

I have a fresh install of 9.10-RC and registered with ubuntu one after installation.
Uploading files through the web page works, but I can not see my files in the Ubuntu One folder in Nautilis and the ubuntuone-client applet (v1.02) can not connect.

When the ubuntuone-client applet starts for the first time the webpage pops up asking me to log in, register my computer and a token appears in my keyring. From then on I can browse and upload files through the web interface, but the client applet shows an exclamation mark.

When pressing connect the following lines appear in syncdaemon.log:

All packages are up to date. I have never been able to connect so far, but this is the first time I could find a clear error message. Please let me know if you need more information from my system.
