Dear all,
I updated to the latest svn version of mitk.
In this version the MainApp crashes with an Exception as soon as I load a
volume and turn on the volume rendering in in the Volume Visualization
Functionality. I digged a little into the source and found the following:
1. The crash is caused by line 49 in QmitkTransferFunctionWidget.ui.h:
tf->InitializeByMitkImage(dynamic_cast<mitk::Image*>(node->GetData()));
>From here the callstack looks like this:

2. I wonder why line line 49 in QmitkTransferFunctionWidget.ui.h is really
needed, because it overrides the default settings that are stored for each
image in mitkDataTreeNodeFactory.cpp.
For my application I removed this line from mitk and everythink works ok (the
bug is still there of course) with the side effect, that the rendering is also
much faster now and the color selection widget is set to the default colors.
