The new imaging subroutines in MSUtil.py (rev 8760, the one with the superuniform and briggsabs weight options) have introduced noise and robust parameters which are not compatible with the 2009 lwimager on my laptop.

My desktop has the 20110628 version and this works OK as it recognises the new keywords. However I am not sure how my desktop ended up with the 2011 version as I've never to my knowledge rebuilt lwimager, and have instead always relied on the version built by the OeRC repository. I track the svn version of everything else.

Both systems are running Ubuntu 10.04 64-bit.

(I appreciate that this is not strictly a bug, and could be remedied if only I knew how to rebuild the lwimager, but it's probably worth checking that the OeRC binary build is shipping the correct version).

Well, since I encourage people to track the latest Cattery, I'd consider this a bug... will add a workaround.

Added workaround in r8762. Added None option to noise. If the GUI is set to robust=0 and noise=None, nothing is passed to lwimager.
