I am trying to track down a discrepancy between the number and search criteria of books generated by the catalog command in the GUI, which is correct, and those generated by the calibredb catalog command line which is incorrect. Both use the exact same search or filter criteria.

However I am stopped dead as all of a sudden my test batch file does not work anymore and yields the less than useful message of "cannot generate a catalog in the EPUB format". I have already spent a great deal of time trying to understand this failure and get on with my testing but have run out of ideas about what the problem really is and how to correct. Can anyone make helpful suggestions as to what I might try next, please? Also adding --verbose to the command line does not seem to add anything to the output.
