Qt Creator: Link to qt5.4 source for debugging

[Serenity]

Hi,

Since Qt5, the QWebKit is crashing, when I load google maps and close the Window before the tiles are loaded.

Now, I want to find a solution for this problem and need to find out, where the error exactly happens. But when I start the debugger and produce the crash, I always saw only assambler code, what doesn't help me.

Is it possible, that the Qt Creator can be setup to be referenced to the Qt Source code and show me that instead any assambler code?

I am using Qt5.4 with Qt Creator 3.2.2.
