What libraries does the binary use (if it uses any shell scripts
to start up, skim them for LD_LIBRARY_PATH setting, then do
LD_LIBRARY_PATH=XYZ:ABC ldd /the/binary
)? Particularly does it use /lib/tls/libc.so.6 
(and /lib/tls/libpthread.so.0) or just /lib resp. /lib/i686 libraries?
If the latter, then it might be using %gs for its own purposes, if the
former, it is unlikely because it would crash when caling some glibc
routine.

If it installs its own segfault handler, then libSegFault.so
will not catch anything. Can you try running that program under gdb?
