Installed via the PPA.
With 0.1 I would get a force close upon starting the Accomplishments app.
With 0.2 It starts fine, I was prompted to sign into Ubuntu One and the app remains blank. I can't see any of the available trophies (opportunities). If I check "Identification" it states that more information is needed but also states "No extra information is required, most likely trouble with your installation."
I have re-installed a couple times via Synaptic but that didn't help.
I am very eager to have this installed as I am trophy kinda guy but so far it's just not happening.
Probably you do not have any accomplishments collections installed. Try installing the two official ones using:
sudo apt-get install ubuntu-community-accomplishments ubuntu-desktop-accomplishments
Afterwards, log out and then back in or kill the daemon using
killall -9 twistd
and then restart the Accomplishments Viewer.
