Bug#943664: xserver-xorg-video-radeon 19.1 (ppc64) crash at startup: undefined symbol: exaGetPixmapDriverPrivate

[Ralf P.]

Package: xserver-xorg-video-radeon
Version: 1:19.0.1-1
Severity: grave
Justification: renders package unusable

Dear Maintainer,

   on the ppc64 architecture the package 
   
      xserver-xorg-video-radeon_1%3a19.1.0-1_ppc64.deb

   crashes the xserver at startup.
   Xorg complains about an undefined symbol: exaGetPixmapDriverPrivate
   
   The bug occured after an update
   from:  xserver-xorg-video-radeon_1%3a19.0.1-1_ppc64.deb
   to:    xserver-xorg-video-radeon_1%3a19.1.0-1_ppc64.deb

   To make sure the bug is in xserver-xorg-video-radeon 19.1.0-1
   I switched several times between these two versions of the package.
   As soon as version 19.0.1-1 is installed, Xorg runs well.
