You may want to try linking the raw unminified files when building Launchpad's 
scripts.  At least the source will be readable.

Untested, but should work:

 $ make clean_js
 $ make jsbuild JSFLAGS='--filetype=raw'


This passes a command-line argument into the lazr-js JavaScript build script 
that changes the input files it selects.

You can find the list of bin/jsbuild arguments by running 'bin/jsbuild --help' 
or by checking the sources under 
eggs/lazr_js-1.5DEV_r191-py2.6.egg/lazr/jslazr/js/build.py.
