I suspect it happens because you do an attack on a unit in the city 
which fails.  The unit is revealed to you when you attack it but is not 
properly hidden afterwards.  Later the unit is moved out of the city and 
away to safety; you don't see this happen.  No further updates are sent 
since you never see the unit again, so the ghost unit remains.

It could also happen because you see the unit move into the city, but 
it's not hidden when it does so.  You do not see it move out, and the 
rest is the same as above.

Reproducing either would be pretty dicey.  I'll take a look at the code 
in a bit.
