Warnings in log files after update to 4.0.13

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 :wink: , so maybe someone can help me where to look for the problem. Thx.

What else is around those warnings.
You may need to temporarily run with logging set to debug to get a
sense of where in the code those are happening. There is not enough
information for us to tell what’s going on from those lines.
