In fact the bug is more extensive.

The critical error message occurs for every file it reads unless each file contains one and ONLY one valid s-expression.

As observed, empty files or files with commented out expressions produce it, as do files which contain more than one s-expression. I discovered the latter by trying to put two valid rules in one file and wondered why I was getting all these "critical" messages.

So even wanting to go into debug mode means putting debug into its own debug.ds file.
