It doesn't crash for all web sites. E.g. http://eric-ide.python-projects.org loads absolutely 
fine. It seems to be something on the web site that triggers the issue.

I tried latest Qupzilla sources and these work fine. That made me believe, that it is a PyQt 
issue (or something was fixed in Qt 5.6 Beta)
