Attached is a backtrace i obtained after rebuilding glchess with
debugging symbols and installing libgl1-mesa-dri-dbg.

It appears that the crash is several stack frames deep into
/usr/lib/powerpc-linux-gnu/dri/swrast_dri.so, so I'm re-assigning this
bug to libgl1-mesa-dri, which provides that shared object.

Feel free to reassign if you think it belongs elsewhere.

Bug#645843: glchess: segmentation fault after loading texture when asking glchess to use 3D mode

2011-10-18 Thread Daniel Kahn Gillmor 
Package: glchess
Version: 1:3.0.2-2
Severity: normal

I launched glchess and got a nice 2D view.  I went into the
preferences dialog box and asked it to show me a 3D view.  It crashed
and disappeared.

Now, every time i try to launch it, it crashes with a segmentation
fault.

I ran strace to see what it's doing before the crash, and it appears
to crash immediately after loading piece.png from the glchess
textures.  I'm attaching what i think is the relevant snippet from the
strace output.
