[Interest] Random crash in QtWebkit / Qt 5.3

[Cornelius Hald]

Hi guys,

I don't have a lot of information yet, but maybe someone here can help
me figure out where that Crash is happening, so I can properly report
it.

I'm using 5.3.0 Beta. The crash seems to happen only (or more often) in
release builds. It happens on Linux and Windows.

So far I have only the following backtrace generated by the crashing app
itself.

My app shows some local static web pages. The crash seems to be
independent of the web page that is currently shown. Sometimes it
happens on page A, sometime on B or C, etc. There seems to be no
pattern.

Here is the trace:

Crash. Received signal: 11

It would be really great if anyone can help me with that.

Thanks!
