Xprint's makefile contains instructions that install this file.
In gentoo distribution this file is placed by ebuild in other directory, so we don't need it in /etc/X11/X11/Xsession.d/
Steps to Reproduce:
Created attachment 133604 [details, diff]
220.127.116.11-r1 ebuild patch
patch to ebuild that modifies makefile
Should be fixed in 18.104.22.168, please reopen if it's not.
