There was nothing which uses the file.

No, the file does not exist when the error occurred.

With Process Monitor I could see, that there was no error in file access.

I then revert all my changes and add them piece by piece, testing after 
each step. I found, that the error was, that I had added a clipboard 
format in filter/source/config/fragments/types/math_MathML_XML_Math.xcu

I have attached the current version to 
https://bz.apache.org/ooo/show_bug.cgi?id=107734. I still have no 
environment for LibreOffice, so Gerrit is currently no option for me. If 
you nevertheless will have a look at it, that would be nice.

Kind regards
