Hi Kenward, May I ask, if you still observe this crash?
If yes, can you try to provide a backtrace? You maybe need to install some debugging symbols (probably python-dbg and maybe the OpenGL debugiing symbols libgl* ...). To get the backtrace, try: gdb python ... (gdb) set logging on (gdb) r /usr/lib/bkchem/bkchem/bkchem.py and then reproduce the crash. When it happens, type: ... (gdb) bt full (gdb) q Maybe the backtrace will tell us more, where the crash is caused (I guess, somewhere in the graphics driver; but we will see).
