Error KIOExec on Kontact Startup

[NoWorries]

For some time now, every time I start Kontact I get an error message for KIOExec. Kontact works fine without any problem for all the actions I need. I do not use Mail, so I am not sure is this error is related to Mail. The text of the error is:

I would appreciate any help to know the reason for this error and a possible solution.
