I posted the issue on stack overflow: http://stackoverflow.com/questions/8692666/rails-3-1-possible-bug-in-asset-pipeline-and-uglifier

I ran into a problem deploying on Heroku do to a failure in the rake task

rake assets:precompile
At the bottom is the error I get if I integrate

Rails 3.1
Jquery calendar: https://github.com/themouette/jquery-week-calendar
Twitter bootstrap
The error happens from uglifier.

I suspect that problem could be related to the inclusion of many localizations for the calendar.

I worked around the error by setting:

# Compress JavaScripts and CSS
config.assets.compress = false
I was not able to examine the files as the temporary files are cleaned up. I also could not get the debugger in RubyMine to stop at a breakpoint.

Any ideas if this is a bug? Any way to get the temporary files to not get deleted? Any way to make the RubyMine debugger work on the rake task (yes, tried the obvious, using EAP 112-291.

rake assets:precompile:all RAILS_ENV=production RAILS_GROUPS=assets rake aborted! Unexpected character '' (line: 21454, col: 0, pos: 641761)
