Meteor 1.9 : no error when malformed template

I am trying Meteor 1.9 version (I used to work with a stack based on Meteor 1.5 version). When a template has malformed HTML (closing tag missing for instance), I used to have an error in the console during the starting of Meteor and that error prevented Meteor to start.

With version 1.9, meteor starts without error, but the malformed Template is not available. Does anyone knows if there anything to do (like setting a debug mode ?) to get information when such error occurs ?

Thanks a lot !
