WWW freezing app on download

Unity Engine

I’m using the WWW to download some test files. Just some .bin file to test some functionality.

But when I download a file from the web (10mb binary for instance). The app freezes after downloading 10~40% of the file. And responds again after the file has been completely downloaded.

Also tested this on just pc and my budget android device. Which both keep responding during file-download just fine.

Anyone else experienced any problems with this?
Tested with Unity 4.5 / 4.6 beta and xcode 5 & 6

Edit:
When I download a valid Assetbundle or something there is no freezing. So musst be something weird with the *.bin files I used for testing.

that sounds really weird. Please create small repro project (perfect would be some simple animation and downloading bin from your server - but i can see that sometimes you need more complicated setup - we are fine as long as you dont drop your whole game on us) and drop case number here
