It sounds like that you might have a slightly older PPA package (we only added the tracking of log files when you start the daemon from the GUI a few days back).
Can you do the following:
1. Ensure the daemon is not running by running: killall -9 twistd
2. Run: twistd -noy /usr/share/accomplishments-daemon
3. Run the GUI by running: accomplishments-viewer
When you run the viewer you should be able to use the Edit menu. Is it still grayed out?
If you wait a few minutes, do you see the trophies appear?
