Some more info:
Now I found the error.log fileâŚ
I have to say quite hidden in
~/.cache/zotonic/log
It seems that Zotero was starting ione time yesterday and writing the console.log and error.log.
All newer tries to start Zotero generated no log files anymore.
Here the content of console.log:

I will try to analyze the mimetypes.erl source, maybe I will find another hint.
