           Summary: Mesa 6.5.3 rc3 crashes Xorg when a composite manager
                    it's killed (replaced)
           Product: Mesa
           Version: CVS
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: critical
          Priority: highest
         Component: Drivers/DRI/r300
        AssignedTo: dri-devel@lists.sourceforge.net
        ReportedBy: [EMAIL PROTECTED]
                CC: [EMAIL PROTECTED]


I'm using Xorg 7.2 with the r300 driver on an ATi Mobility 9700 and I've
upgraded mesa to 6.5.3 rc3 (but this happened also with older git), and now
when I launch a composite manager like beryl or compiz all works well, but if I
want go back to another composite manager (using something like "kwin
--replace"), or simply if I kill it, Xorg crashes and this is the Backtrace I
get:

(**) RADEON(0): RADEONSaveScreen(2)
(II) RADEON(0): Damage tracking initialized for page flipping
(II) XAA: Evicting pixmaps

DISPATCH ERROR! _glapi_add_dispatch failed to add glGetVertexAttribPointerv!

Fatal server error:

(II) AIGLX: Suspending AIGLX clients for VT switch

Maybe should I upgrade also Xorg to git? I doubt it is really needed because
all works quite well before replacing my X-composite manager...

I've no debug dri libs installed here, maybe they can help?
Again, I've compiled only the dri modules that I need (r300 and radeon), I
think  this is correct, isn't it?!
