cron.daily/logrotate: cat: /var/run/landscape-client.pid: No such file or directory

Binary package hint: landscape-client

I received the following email from the logrotate daily cron job:

/etc/cron.daily/logrotate:
cat: /var/run/landscape-client.pid: No such file or directory
kill: 2: Usage: kill [-s sigspec | -signum | -sigspec] [pid | job]... or
kill -l [exitstatus]
error: error running postrotate script for /var/log/landscape/sysinfo.log
run-parts: /etc/cron.daily/logrotate exited with return code 1

landscape is not currently running:

mizar:[~] ps aux |grep landscape
mdz 30063 0.0 0.0 2336 788 pts/4 S+ 16:29 0:00 grep landscape

Presumably the logrotate script should check whether landscape is running before attempting to signal it.
