Cinnamon on ATI - not what I expected (?)

(cinnamon:10966): Gdk-WARNING **: The program 'cinnamon' received an X Window System error.
This probably reflects a bug in the program.
The error was 'GLXBadRenderRequest'.
  (Details: serial 180 error_code 140 request_code 131 minor_code 1)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

Some info about the system:

maybe this bug https://bugzilla.novell.com/show_bug.cgi?id=728646 ?

and it seems to be discussed in this thread http://forums.opensuse.org/forums/english/get-technical-help-here/applications/470559-how-do-i-install-proprietary-radeon-catalyst-driver-2.html

Than you for refering me to a bug I helped to solve and to a thread where I provided the most explanations. lol!

This problem is different. It affects only cinnamon (so did the nvidia bug btw). Gnome-shell is OK. I said “not what I expected” because after the nvidia bug aready widely discussed in the forum, I was hoping to not run into a similar problem with ATI. I actually needed a fresh install on an ATI machine to test version 4.0 of atiupgrade (it’s already available in my repo and seems to work) and rewrite the article about atiupgrade, which needs update. Now I’m kind of wondering why cinnamon doesn’t start. I wouldn’t have noticed if I had not installed cinnamon on this machine. I hope @ketheriel will drop in when he sees this thread. Otherwise I’ll send him a PM and fill out a bug report as soon as I have established that it’s not a misconfiguration on my side - gtk3 is perfectly capable to prevent the wm from starting because of an innocent mistake in the theme files. I will make sure it’s not the case, but I doubt it.
