GLXINFO of radeon

Hi, I was trying to test the new kdenlive development build I noticed that it
wouldn't even start with DRI_PRIME=1 kdenlive.
I immediatedly got a SIGABRT
Same happened with an easy example program from the Qt project "openglunderqml"

"LANG=C R600_DEBUG=cs DRI_PRIME=1 QSG_INFO=1  '/home/paul/hybrid
test/build-openglunderqml-Desktop-Debug/openglunderqml'                         
QML debugging is enabled. Only use this in a safe environment.                  
openglunderqml: dri2.c:518: dri2_allocate_textures: Assertion
`drawable->textures[statt]' failed.                                    
Abgebrochen (Speicherabzug geschrieben)"

As Xonotic worked more or less ok on the radeon I filed a bug report at the Qt
project https://bugreports.qt.io/browse/QTBUG-45686
Laszlo Agocs from the Qt project states the following: 
"Might be a difficult one and not just because we lack any such hw to test on.
Cannot do much when glXMakeCurrent() crashes deep inside the driver.
Any chance for a backtrace with symbols? In the absence of that running with
QSG_INFO=1 could be helpful too.
Anyway, it's most likely happening in QGLXContext::queryDummyContext() where we
attempt to make a pbuffer surface current in order to query a few GL things.
