Same thing happened to me on my Dell Optiplex GX110 running Ubuntu 7.1.
Showed an item count but Inbox was emtpy. No filters were in use. Still
empty after deleting all search folders except Unmatched. I noticed
however that the search folders had the emails that should have been in
the Inbox. So
Public bug reported:
When you select Applications>Accessories>Dictionary and type in Übuntu,
no results are found. Results are there for other Linux distros such as
Red Hat or Debian. Ubuntu needs to be added to this dictionary also.
