Rails - Jul 2014 - Application trace in the error page for a Rails engine

I'm developing a Rails engine, and when debugging an error through the 
default Rails error page, I find that the Application trace shows nothing, 
while Framework trace and Full trace show the trace.

Is this intended for an engine?
