/etc/cron.daily/man-db.cron: gzip: /usr/share/man/man1/shutter.1.gz: not in gzip format gzip: /usr/share/man/man1/shutter.1.gz: not in gzip format $ rpm -qa |grep shutter shutter-0.87.2-1.fc15.noarch
[andre@compaq-pc ~]$ file /usr/share/man/man1/shutter.1.gz /usr/share/man/man1/shutter.1.gz: troff or preprocessor input, ASCII text [andre@compaq-pc ~]$ It appears the file is simply not gzipped. If I replace /usr/share/man/man1/shutter.1.gz with its gzipped version, then "man shutter" works normally.
