jsonview-safari interferes with safari's interpretation of file upload responses

[ddiguru]

I've had an issue that has plagued me for some time. Any time i would get a proper JSON response to a file upload, safari would return server error in ExtJS when attempting to parse the responseText. Come to find out this plugin was doing something that caused this problem. Here is a URL to test this problem out.

I'm using Mac OS X 10.11.3 w/ Version 9.0.3 (11601.4.4)

I have your 1.7 plugin installed (i even tested this out with the Ace plugin too)

Try to upload a file to that demo, and w/ the plugin installed and enabled you will get a server failure. If you use safari's inspector, you'll note that valid JSON is being returned. Disable the plugin and retry and it works. This was a very odd problem, and one that has stalked me for some time.
