Minfied respond.js does not work in unpatched IE7
I haven’t the full reason for the problem – exactly which implicit line ending that goes wrong – or whatever else that is broken. But the (almost) fix is – don’t use the minified version. At github you can get either version as (respond.min.js or respond.src.js). Go for the latter, it is the non-minified one.
In my unlatched IE7 I get a somewhat stocastic behaviour. When just browsing it first fails but a reload makes the page load properly.
Other browsers – including Safari/Ipad and built-in/Android seems to work alright with the minified version.
