Can you install debug(info) package for Xorg and build radeonhd with debug info (-O0 -g3)?
I.e.: `CFLAGS="-O0 -g3" make` ?
Could not get a decent bt yet even though I did rebuild radeonhd etc. Perhaps the Xorg.log bt doesn't work well with debuginfo? Need help in getting debuginfo to work.
This looks very similar to bug #25281, F12's X'd segfaulting in a very similar way when compositing is enabled. The conclusion there was that the problem was with EXA, but I'm not sure where to go next.
Just to be sure: durign normal use I have no issue with radeonhd/Xorg/etc. Just when trying to enable the Compiz thing via the Fedora prefs.

Maybe radeonhd just doesn't check for source-only (solid or gradient) pictures, which have pPicture->pDrawable = NULL.
Does this issue occur with the preferred ati driver (xf86-vide-ati)? If so, please move this to the Driver/Radeon component. Development of radeonhd has pretty much halted and development focus is on the ati driver. Please see http://www.x.org/wiki/radeonhd If the issue does not exist in the ati driver (or if there is no response to this message), this bug will be closed as WONTFIX unless someone contributes a patch.
Switched to radeon. Upgraded to fedora 15 with Gnome 3.0. Gnome does not really allow me to use compiz to the fullest yet.
