qdoc3: Trying to find a bug that causes a crash.

It doesn't crash on OS X, but it does on some other platforms.
If you run into this crash running qdoc3, you can work around
it by commenting out line 1539 in tools/qdoc3/htmlgenerator.cpp
The line to comment out is:
        generateQmlInheritedBy(qml_cn, marker);
