Very good finding. Something I hadn't considered ...

probably in xserver-xorg-video-nvidia ... and probably a nonobvious 
dependency on something that gets dlopen()ed ... and the dlopen() error 
silently got ignored, but the symbol used anyway.

Can you take a look at
   lsof -p <XORGPID> | grep lib
to see which nvidia libraries are loaded into Xorg?
If you identify one (or more) of newly installed library packages, can 
you uninstall nvidia-driver-full (but keep the dependencies) and the 
library in question to see if the segfault returns? Maybe needs some 
iterations ...

And thereafter for verification, remove everything added by 
nvidia-driver-full and just add that one library that seems to 
cause/solve the segfault.


Thanks
