Comment (by dd32):

 In general, I think we should leave this in place so  that Developers are
 made aware of their error.

 it's unwise to pass dynamic strings to add_filter/add_action, as it can
 have security implications as well.

 Can you track down why the filter has an empty string as the function
 callback instead perhaps?
