I tested this in Linux version in Calibre, and it seems to give the error message in OP if the "Unknown" is typed so that first letter is uppercase.
If the whole string is lowercase, then saving works, but if I change it back to capital U, then it breaks again. Note that I am talking about Author - field, not author_sort.
Strange
Edit. Tested again by editing one book and renamed author to Unknown. Saving to disk failed. Renamed author to "unknown" and it worked. So it seems to be bug
