Starting konsole from a terminalemulator, gives amongst other output:
konsole: cannot chown /dev/pts/1.
Reason: Operation not permitted
konsole_grantpty not installed root-suid
konsole: chownpty failed for device /dev/pts/1::/dev/pts/1.
       : This means the session can be eavesdroped.
       : Make sure konsole_grantpty is installed in
       : /usr/bin/ and setuid root.
konsole_grantpty not installed root-suid

This is ofcourse a bogus messages, since this isn't needed with devpts, but for
some reason konsole doesn't detect this and screams. I'm afraid this could
confuse users and lead to false bugreports.

Quick fix: don't include konsole_grantpty in the RPM, instead just make a
symlink named konsole_grantpty to /bin/true.
IOW put this in the install part of the spec:

rm -f /usr/bin/konsole_grantpty
ln -s /bin/true /usr/bin/konsole_grantpty

But you need to adjust this for the install root ofcourse.
Let me know if you want this bug to be reported upstream.
