Got "/etc/profile.d/colorls.sh: line 10: [: : integer expression expected" from /etc/cron.daily/cyrus-imapd with coreutils-6.10-f.fc9. The problem is that the referenced line assumes that a particular infocmp | sed command will return a number, when I suspect that it can also return an empty string (e.g., if TERM isn't set). The easiest fix is probably to use = instead of -eq.
Thanks for report, will fix that in next rawhide build...
Fixed in coreutils-6.10-7.fc9 .
