As decided on in #ubuntu-desktop just now, we'll not ship this until
ghostscript runs on an upstream snapshot of lcms2. We won't take
ghostscript's forkish of lcms2 as our lcms2 package.

Thank you very much for applying the changes, unfortunately, something
went wrong in your application of the patch. I have built Ghostscript
9.07 against the patched library and it segfaults on most PDF files.
Here is the gdb backtrace:
till@till-raring:~/ubuntu/ghostscript/ghostscript-9.07~dfsg$
Here is the original GS command line which lead to the stack trace above
gs -sDEVICE=cups -r600 -dcupsColorSpace=1 -sOutputFile=../z
~/altona_technical_1v2_x3.pdf
The input PDF file is attached.
** Attachment added: altona_technical_1v2_x3.pdf
I have sent the ghostscript 9.07 package to my PPA for testing:

Package: ghostscript 9.07~dfsg-0ubuntu1~ppa1

I succeeded to fix the patch for lcms2, comparing the lcms2 which comes
with upstream Ghostscript and the upstream source tarball of the Ubuntu
lcms2 package. The debdiff with the resulting patch is attached. With
this version Ghostscript 9.07 is absolutely stable (tested ~20 PDF
files).
Please
I have also sent the new patch to the upstream developers of Ghostscript
and they are contacting Marti Maria from LCMS now to make sure that the
upstream version of the changes works correctly.

The Ghostscript developers did also some optimizations of LCMS2 for
Ghostscript. These optimizations were also made available for upstream,
see:
https://github.com/robinwatts/Little-CMS/commits/artifex
The attached patch contains the fixes from above and the optimizations.
