As Alan Pater (#63) notes, in Lucid beta this issue is harder to work around than in Karmic due to the right-click and favicon area click trick no longer working. It's also very random, the address bar will start auto-completing again after some time (or some actions, but nothing I can pinpoint).
For me this is the most visible and work-flow interrupting bug in the beta so far.
