[Owncloud] Broken fileupload on IE

[Arthur Schiwon]

Hey,

in OC 4 file upload is broken on IE (at least for IE 8 and 9), despite 
it has worked on OC 3. This is somewhat critical unfortunately.

IE fires an JavaScript error: "Access denied".

It occurs between when this is triggered:
$(this).parent().children('.file_upload_start').trigger('click');
(in apps/files/js/files.js)

file_upload_start is the file input element. IE is very strict about 
this type of element and hardly permits JS interaction with that.

OC 3 does not differ much regarding HTML structure. However, using IE 
the cited line is not being triggered. Confusingly, commenting out that 
element makes it unusable.

I am pretty much dark with that. Does someone of you have an idea?

Cheers
Arthur
