QUrl::fromUserInput behaves poorly when given an invalid input

I apologize that I may have placed this in too many Components above. I was not clear of one or two that applied, so I selected any that were close.

I am reading from a database a URL that was entered by a human, and needs to be applied some fuzzy logic to try to determine what was meant. Specifically, anything a browser might try to "correct" the URL is what I want to try to correct, as it will be interpreted exactly by a browser.

Upon the recent (4.6.x) existance of QUrl::fromUserInput(), I thought I would try that, as I was having a problem with the QUrl(QString) constructor doing "the wrong thing".

I'm now getting a different wrong thing. If a URL has a hostname that is considered invalid (in my case, 'pictures..ie'), the "http://" prefix before it will be adapted into "http//", and then considered a hostname itself. So:

Input argument 'google.com' produced URL 'google.com' via construction from QString, URL 'http://google.com' via fromUserInput.
Input argument 'http://google..com' produced URL 'http:' via construction from QString, URL 'http://http//google..com' via fromUserInput.

It would seem reasonable to attempt to collapse double-dots in hostnames within QUrl::fromUserInput().

Thank you.
