Description of problem:
Logrotate on RHEL 5.7 seems to have the bug described by Fedora bugzilla  517321 and 542538

Version-Release number of selected component (if applicable):
logrotate-3.7.4-12

How reproducible:
Every night if you have an error in your logrotate config

Steps to Reproduce:
1. Install logrotate
2. Install e.g. cobblerd and never run the daemon so the log files are non-existent
3. Wait for overnight
  
Actual results:
Get error message in logs e.g.
Oct  3 04:02:05 dmckenzie logrotate: ALERT exited abnormally with [1]
plus a mail saying something like
error: stat of /var/log/cobbler/tasks/*.log failed: No such file or directory

Now ps fax shows forever until killed

 9467 ?        S      0:00  \_ crond
 9468 ?        Ss     0:00      \_ /bin/bash /usr/bin/run-parts /etc/cron.daily
 9901 ?        S      0:00          \_ awk -v progname=/etc/cron.daily/logrotate progname {?????   print progname ":\n"?????   progname="";????       }????       { print; }

Expected results:
No logrotate hang
