Sorry, I haven't received a chunk of this thread for some reason, so I 
hadn't seen these instructions.

Tried what you said and produced the following bt:

#0  0xb7fd5430 in __kernel_vsyscall ()
#1  0xb74a36d0 in raise () from /lib/tls/i686/cmov/libc.so.6
#2  0xb74a5098 in abort () from /lib/tls/i686/cmov/libc.so.6
#3  0xb7f3f97d in fault_handler (sn=11, si=0xbfbf1e7c, ctx=0xbfbf1efc)
    at ./sighand.c:49
#4  <signal handler called>
#5  0xb6bf4b60 in ?? () from /usr/lib/libGLcore.so.1

Unfortunately, the nvidia packages don't come with debugging symbols so 
I can't tell you what the missing fn in line #5 should be.  I'll try to 
isolate the point in the code where the crash actually happens.  At the 
moment, I haven't had much luck with that.  Incidentally, when I run 
fluxus through ddd the line pointer jumps all over the place.  It 
doesnt' step through each line in order as I'd expect.  Are there some 
optimisations going on that are confusing the debugger?  Is there a 
--for-debugging flag that I need to switch on in scons?
