Having trouble clearing a QTreeWidget.

[Nyphel]

Oki, I've attached the source code in the previous post .

So, how may I produce the fully backtrace for my code ?
I'm under Windows XP Pro SP2, using Eclipse as text editor.
I've recently added the Qt Plugin for Eclipse in order to managed my .pro file, to use the API code completion, to build and run my project...

But I've no idea about what concerns the backtraces/debugger functionalities of Qt and/or the Eclipse integration.

My Qt is compiled in release/shared configuration.
Should I rebuild it in debug/shared configuration ?



PS : I'm sure that the crash isn't caused by a Thread.
The application crashes when no Thread is started, I can make it crash just after the launch if necessary. My thread are only started on user ask, by clicking buttons on the interface et traces are displayed on the cout when the run() method is called.
Moreover, I've decided that no thread would modify the QTreeWidget. So only Listeur and Interface_impl classes can modify the QTreeWidget, I prefer that...

But I understand why the backtrace is necessary
