Follow-up Comment #1:

This isn't an Octave bug, but rather a ghostscript or gl2ps bug.  The problem
is that rgbstr is 120,000 elements and the maximum size for a string is 65535.
 See the table Architectual Limits 3.1 in the Ghostscript documentation
(http://ghostscript.com/doc/8.54/Language.htm)

ghostscript sources have been patched to increase the maximum string length in
Aug. 2012
(http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=86f9af6937e76e10a7adad201b06c337b1a9240b).
 So you could always build from source to get a ghostscript that works. 
Eventually this will trickle down into Linux distributions as well.

Alternatively, gl2ps could be hacked to use .bytestring rather than string
which does not have a limit on size.  However, that would make the output
ghostscript-specific, rather than PostScript compliant, which is probably not
a good thing.
