discrepancies in package status between 'aptitude search' and 'dpkg -l'

[Adam Funk]

I just noticed something weird in my package lists; "aptitude search"
didn't show wine as installed (I thought I remembered installing it on
this machine last week).  Then I tried 'dpkg -l', which showed the
packages as installed.  Then I tried 'aptitude search' with a slightly
more specific pattern, and got different results.  (Finally I tried
the first command again.)

What the heck?!?
