Auto Config URL shows no warning that proxy.pac could not be found

[GoogleCodeExporter]

If you enter an invalid Auto Config URL there is no warning that the file/url 
does not exist or can not be opened/found. In my case a simple German Umlaut 
was the problem (the path was correct but not in the expected encoding)

Example: 

Not working: 
Auto Config URL: file:///home/andreas/Dokumente/Geschäftlich/proxy.pac

Working: 
Auto Config URL: file:///home/andreas/Dokumente/Gesch%C3%A4ftlich/proxy.pac

There was no hint, that the first variant did not work... except for the fact 
that I could not access the internet ;-)
