Comment # 2
on bug 93352
from Jürgen Scholz
After installing (possibly unnecessary debug symbols and source files):
* aptitude install libgl1-mesa-dri-dev:i386 libgl1-mesa-dri-dbg:i386
libgl1-mesa-dri-dbg xserver-xorg-video-radeon-dbg libgl1-mesa-dev
* cd /usr/src; apt-get source libgl1-mesa-dri
* ln -s /usr/src/mesa-11.2~git151211033900.64c59b0~padoka0/src/mesa
/usr/src/mesa
The backtrace seems to be complete:
Program received signal SIGSEGV, Segmentation fault.
