This bug report originated from issue QTBUG-3923
<http://bugreports.qt.nokia.com/browse/QTBUG-3923>

--- Description ---

Webkit crash when there is an object in the html if the type of this object contains the character plus (+).

Here is the minimal example to reproduce the problem:

int main(int argc, char **argv){
  QApplication app(argc, argv);
  QWebView view;
  view.setHtml("<object type=\"application/rss+xml\"></object>");
  view.show();
  return app.exec();
}

Reproducable in trunk

Created attachment 50096 [details]
backtrace of qt-master branch bundled webkit ("system webkit")

I cannot reproduce this crash with trunk WebKit of today. Tested with Linux 32bit and Mac 64bit.

I can reproduce it with WebKit from qt master branch compiled few days ago. Linux bt attached for interested parties.

Qt master is ~ Qt 4.6 when it comes to src/3rdparty webkit. Could not reproduce this in trunk.
