The best way is "Find -> last error" but it sometimes doesn't find the
error. A more complicated way would be to replace [urn] with a
debugging abstraction, that also prints, what's coming into its
inlets. [print $0-urn] can help with finding the right urn. And if you
want to get fancy you make it a graph on parent abstraction that shows
the value of $0 on the parent.

You could either use an "urn.pd" and try to disable [urn] by not
loading it's library and/or moving the single external file out of the
way temporarily, or use a different name like "urn_debug.pd" and
replace all occurences of [urn] with the new abstraction's name. I
recently posted a little Perl oneliner here to rename objects in Pd
patches, search the archive for "perl".

Ciao
