Ghostscript stopped with status 255

Hello,
my cups stopped printing and after poking here and there, the best I could find is (excerpt from cupsd logs in debug mode):

After checking with GS folks, they told me:
'You can't use an sRGB ICC profile with a monochrome device (pxlmono), the colour spaces are not the same. If the device were pxlcolor (an RGB device) then that would work but for a monochrome device you need to use a Gray ICC profile. The sgray.icc profile would work for example.'

Could you tell me how to modify that or probably this is something that should be upstreamed into the project?

Thank you.
