It took me a while to locate this trigger since it didn't have a label. It would help if the path was used to help locate the trigger there is no label.
Hmm. Wasn't there a change a while back to include the trigger match pattern in errors? I must be misremembering, because I can't find any note about it.
A work-around is to make the trigger call a script in a script file (and not send-to-script) which would then give you the script function name and a line number.
