[Ogre2.0] Segmentation fault

Hi!
In the context of the MyGUI pass creation i get in the examples and in my program a segmentation fault in the:
targetDef->addPass(Ogre::PASS_CUSTOM, MyGUI::OgreCompositorPassProvider::mPassId );

But the most bugest thing is that in the examples it segmentates only if the ogre.cfg doesn't exist and the default config dialog is displayed.

* Initialise: RenderManager
RenderManager successfully initialized
* Initialise: DataManager
DataManager successfully initialized

Program received signal SIGSEGV, Segmentation fault.

Using the Ogree411a480d3aa (v2-0) v2-0-0RC1

This happens in Debug and RelWithDebInfo under Linux. I din't found nothing strange in the mygui code.

Thaks for your time!
