[rt-users] Warnings in log files after update to 4.0.13

[Weiss, Robin]

Hi !

We updated RT to 4.0.13, everything works, but there are now warnings in the log files.
For example:

Jul 24 15:22:19 rt RT: Use of uninitialized value in string eq at (eval 1895) line 1. ((eval 1895):1)
Jul 24 15:22:19 rt RT: Use of uninitialized value in string eq at (eval 1926) line 1. ((eval 1926):1)
Jul 24 15:22:28 rt RT: Use of uninitialized value in string eq at (eval 1882) line 1. ((eval 1882):1)
Jul 24 15:22:28 rt RT: Use of uninitialized value in string eq at (eval 1913) line 1. ((eval 1913):1)
Jul 24 15:22:33 rt RT: Use of uninitialized value in string eq at (eval 1946) line 1. ((eval 1946):1)

Perl is not our native language ;-) , so maybe someone can help me where to look for the problem. Thx.
