Okay... I can produce a segfault in a windows domain with vnc, but not
in a linux domain in text mode.

'backtrace' says:

"
#0  0x0000000000409b25 in ?? ()
#1  0x000000000046c041 in ?? ()
#2  0x000000000040b6d6 in ?? ()
#3  0x00002b43022004ca in __libc_start_main () from /lib/libc.so.6
#4  0x0000000000404bba in ?? ()
#5  0x00007fffa94a6f08 in ?? ()
#6  0x0000000000000000 in ?? ()
"

Which isn't helpful to me. Is there another command I can try to give
something more useful? Perhaps I need debug info compiled in...

Thanks

James
