doubled log messages

[Harry]

All messages generated by krb5kdc and kadmin are being logged twice, one
right after the other in their respective log files.  Weird, huh?

kdc.conf snippet:

   [logging]
     default = FILE:/var/log/krb5libs.log
     kdc = FILE:/var/log/krb5kdc.log
     admin_server = FILE:/var/log/kadmind.log

Running these RPMs on RHEL v4:

   krb5-workstation-1.3.4-12
   krb5-libs-1.3.4-12
   krb5-server-1.3.4-9

Any help appreciated.
