I just played it through. I created a note in Notability named “Tüüüst” (don’t question it ), which would then automatically get backed up as a PDF to the WebDAV server.
The seafdav.log states an Internel Server Error with less information than I would have hoped for. Here is the relevent part of the Log:

The other logs weren’t any more helpful than that either. The seafevents.log just says the file has been added (which is true, it’s just empty) and the other logs do not mention anything of this.
I hope this helps you more then it helps me.
