Obscure exception if last line of js file is a comment

[cgriego]

If the last line of a JavaScript file is a comment, bundle_fu fails to generate the cache file and throws an obscure exception.

Exception message: comparison of Fixnum with String failed

This issue is 1year old, but anyway I will post a comment about it.
I was having the same problem some minutes ago, and I noticed this happens because of a minor incompatibility with Ruby 1.9.x in Bundle-fu's own JSMinimizer code. An easy workaround would be installing Packr (gem install packr), as bundle-fu will detect this package as installed and use Packr's compression code.

I encountered this error with Ruby 1.8

Ohhh.... that is not what I expected. Do you still have the full trace of the exception?
