up2date channel 7.2.93 currently contains ghostscript-6.53-7 and gimp-print-cups-4.2.0-9. The two conflict because both own the same file, /usr/share/man/man1/gimpprint-config.1.gz
You need the ghostscript, gimp-print-cups, and hpijs packages in rawhide. *** This bug has been marked as a duplicate of 62151 ***
