We have the same issue.

Thanks for your reply RRUKI.i still do not know how to solve this issue...and you?
Hi guys, as a quick fix try merging js in the Magento admin, under
Hope that helps ?
I actually receive this bug when I merge the JS files? Once I unmerge them, I can upload images with no issues. Any help will be greatly appreciated, unless you have to unmerge the JS files to upload images which does not seem quite right.
My issue still persists. Tried different browsers, JS CSS unmerged, already on the live server, flushed caches and server PHP, but still no luck. So sad.
My issue is finally fixed. Yay
