Hi,
I added a null pointer check so it shouldn't crash anymore but as I
can't reproduce this with qt3 I hope the rendering is also correct.

Hi Toni,
the stack trace helps a lot, thanks.

This causes the crash. Apparently the CGFXChunk is the only component
that needs this, which is why it never happened before.

The problem is that updateParameters implicitly assumes to only be
called from activate/changeFrom/deactivate, which initialize _action
before they handleGL is called. validateAllGLObjects() doesn't do that,
and it crashes.
Andreas, can you take a look at that?
