The reason you don't get the error when you run the transformation from your
editor is probably that you're using an earlier version of Saxon - the rules
for EBV (effective boolean value) were changed very recently to introduce
this error.

I'm afraid the line number information here seems to be off: there's nothing
on this line that's calculating EBV directly. It might be that this line is
causing a deferred evaluation of the variable $ont and that the error is in
the code for initializing that variable (just a guess).
