This crash appeared as of r163037.

Test Scenario.
1. Run Debug MiniBrowser
 > Tools/Script/run-launcher --debug --gtk -2 http://www.google.com
2. Crashes at WebCore::URL::URL() because "url = http://www.google.com" but "m_string = http://www.google.com/"

If we always put "/" at the end of URL, there won't be assertion failure at URL::URL()

This patch fixes the issue by using SoupURI API to create a URL object to be passed to loadRequest()

This broke /webkit2/WebKitWebContext/uri-scheme

/webkit2/WebKitWebContext/uri-scheme: **
ERROR:../../Tools/TestWebKitAPI/gtk/WebKit2Gtk/LoadTrackingTest.cpp:30:void loadChangedCallback(WebKitWebView*, WebKitLoadEvent, LoadTrackingTest*): assertion failed (test->m_activeURI.data() == webkit_web_view_get_uri(webView)): ("echo:hello world" == "echo:hello%20world")

I think the problem here is in the test, not in the code, since "hello world" is not a valid URI (it should be normalized to "hello%20world" to become one) and so that's why the WebView, after this patch landed, is returning a mismatch in comparison to what the test class has stored.

So, unless there's a good reason to support URIs such as "hello world" or "foo bar" in this test, I'd suggest to just update the test to use "hello-world" or "foo-bar" in these two cases, so that we do not need to either artificially unnormalize whatever valid URI comes from webkit_web_view_get_uri() nor to normalize the URIs used in these test cases.

Yes, I think you are right.

Sounds good to me
