[Motmot] change in usage of imops.mono8_to_rgb8?

[John Bender]

I've replicated this bug on Hardy 32-bit, but it ironically doesn't
appear to be in Jaunty 64-bit. I recompiled imops from SVN revision
394 (on Mosca) the error went away. However, I had to mess around with
the import statements and maybe the sys.path to get the compiled
rather than the packaged imops. HTH!
