Is this "normal" behaviour for the current mnemonic?

Finally managed to download the thread-safe X11 libs and installed them,
download a new mnemonic as well (at 15:50 GMT). Running it gives the
following under my RedHat 4.1 - Kernel 2.0.27, GCC 2.7.2.1 system:

bash$ mnemonic sample.html

I know this is still really alpha software, but is it supposed to segv
before showing some signs of life?
