Problem when minimizing the js expression "+ ++"

Problem when minimizing the js expression "+ ++"

Dear team.

I download today the new release of JQuery-UI 1.8.1 and when change it into ours projects, I detect a problem using Firefox. When I search the problem, I find that the error is that the expressión "+ ++" used 4 times in the jquery-ui.1.8.1.custom.min.js create a problem when ours systems re-minimized the expression directly to "+++".

We are using the jsmin provided by  http://github.com/rgrove/jsmin-php/.

Now, I fix the problem addind a +(++...) in the minimized js.

Josep.
