Trouble debugging QtCreator itself

[Rexona for men]

To find the cause of my problem (https://bugreports.qt-project.org/browse/QTCREATORBUG-9789 ) I tried to debug QtCreator by myself (at least it's better than just sitting around). So I got the source code and opened it in QtCreator to start debugging it.

However, after some time the debugger stops in line 950, pluginspec.cpp:
@PluginLoader loader(libName);@
Its the QmlDesignerd.dll

Whatever I try, I can't get any further.
Just starting QtCreator without debugging works perfectly.

Nevermind, after a lot of time, it worked.
Could be a bit faster though .

Any hints what went wrong?

No idea really, at the moment it takes much less time, approx. 30 seconds.
When I tried it yesterday, it stayed in the line above for over five minutes and I restarted it several times.

It's somehow weird, but at least I can debug it now..
