[Lucid] ubuntoone-client unable to connect, ubuntuone-login causes high CPU load. reproducable

Binary package hint: ubuntuone-client

When I try to start ubuntuone-preferences the options dialog/webpage never shows up.
Instead ubuntuone-login causes a high CPU load up to 100%. See ps output below.
There is also a third process running bound to the bash, which PID is increasing forever.

If you don't kill all 3 processes with the System Monitor, the third process will be still there after reboot
and preventing ubuntuone-syncdaemon to start on your next try.

ubuntu-bug 1480 apport and
additional syncdaemon.log with debug informationen attached.

Since this bug is reproducable i could add more informations if needed.
