"* nil" record in Logs for script unknown

[pchytil]

Hi,

I am having problem with with "* nil" entries into the Logs. Every time any script runs (mostly using event scripts) getting record in Logs with Time, script unknown, * nil. (see in attachement). It does this also for periodically ran scripts too.
If I disable script running the entries in Logs stop. Could you please provide some guidance what to check/fix? Or if I should provide more info, scripts, access...

   
Thank you,
Pavel
