Error in latest Chrome (38.0.2096.0)

I get the following error in the current version of Chrome trying to load the demo page:

Uncaught ReferenceError: Invalid left-hand side expression in prefix operation

the line number with the error refers to the line 7718 of jszip.js:

if (--(count[len]) === 0) {

I've confirmed this error on mac and windows.

That's a chrome bug. I've released update for pako. The only thing that should be done - rebuild jszip with updated pako sources.
