Share and send by email fails - error message

When sharing a file by creating a static link and sending via email, there is an error result. E-Mail settings should be correct as I receive testmail (button beside email-settings) and activitys as defined.

Version: 9.1.1 (release channel: stable)
Installation was clean, no update. I am using a customized theme based by example theme.

This is owcloud.log (cleaned)
