Script5 access denied in IE9 in same domain

Question

I'm developing a site in django, which uses a jquery multi file upload plugin.

When i register to my site, a confirmation email is sent to my gmail account, i click the activation link and my website is opened in a new tab. I login, then I try to upload a file and it fails in IE9... F12 says "Script5 access denied"

However, if I type the link in the URL address bar instead of clicking the link in my email it works perfectly. It allows my to upload anything I want.

Im testing in a development server, and the host name is http://192.168.0.1:8085

My problem is that when i access my site via the email link, it just doesn't work... i checked the headers and the only thing that changes is that when i open the page from my email link, there is one extra header, HTTP_REFERER = http://192.168.0.1:8085:/activate/16834e18a471d4f654aa763b2b22f203/ but besides this, i cant find anything else that could be causing the problem... and i cant understand why when i type the url it works correctly.

The jquery multiupload plugin im using is: https://github.com/blueimp/jQuery-File-Upload

My script is: http://pastebin.com/2JE8Qrnm

hm... what jumps into my mind first:

try to add:

response['p3p'] = 'CP="IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT"'

and/or:

response['Access-Control-Allow-Origin'] = '*'

to your response.
