That was one bug.  There was actually another bug.  Gerald K. Dobiasovsky
suggested some other bugfixes back in July, 1999 which fixed bugs in
ultra_wide_angle and the four cylinder cameras.  I have never used any of
these cameras, so I never came across the original bug nor do I know exactly
what the bugfixes change.
