Binary package hint: unity
If you hit Alt-F2, and enter "ubutnu-bug unity", "ubuntu-big unity", or "unity-bug ubuntu", nothing happens. On several occasions, I have thought that the ubuntu-bug program was simply slow to start, wasting several minutes patiently waiting before finally discovering my typo.
I think a simple error message "Could not start 'ubntu-bug'" would greatly help in these situations.
