Can you send a backtrace?  This can be done by doing the following:

$ gdb ./spcagui
...
(gdb) run
...
[SIGSEGV]
(gdb) backtrace
[send us the stuff you get here]

This will show us the functions that were being called at the time the
segfault occurred.  I'm not sure if it's compiled with debugging
symbols by default; if it is, then we may need you to re-send the
backtrace after compiling with -g, but just send us the backtrace for
now.
