           Summary: [Qt] Avoid ErrorPageExtensionOption to hold empty
                    'url' field
           Product: WebKit

          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: NEW
          Keywords: Qt
          Severity: Normal
          Priority: P2

In some cases, QNetworkReplyHandler's m_reply holds an empty url.

m_reply->url(); <--- empty.

it happend for example in some non-successful page loads. e.g. if one do:

<quote>
frame>setUrl("http://any.thing.invalid.here/");
<quote/>

When it happens, the ResourceError passed up to FrameLoadClientQt by
QNetworkReplyHandle::finish (via MainResourceLoader -> DocumentLoader ->
FrameLoader) will fill ErrorPageExtensionOption's url field with an empty url.

it might not be a helpful situation for client application handling error pages
