Sorry, the bug has been reported against our sle12 business product (closed
beta program). I'm wondering that you could access it at all. I've meanwhile
cloned the bug to the openSUSE bug area, which should be accessible by
everybody - after registering to Novell's bugzilla. :-( Sorry for that
inconvenience.

I didn't try to upstream this yet, since I wasn't convinced about the full
correctness of the patch. It doesn't make use of a threshold and a verbose
level which is done in src/glx/dri_common.c:dri_message(). Looking at
__driUtilMessage() more closely a verbose level isn't given anyway. So
probably the patch isn't that bad.

If you believe the patch is ok, please feel free to push it. You do have my
"Signed-off-by: Stefan Dirsch <sndirsch at suse.de>".

Hope this helps.

Thanks,
Stefan
