Hmmm, there is no timeout.

Your system does not define NSIG so there is no proper way to print
the signal name from within a signal handler.

If it is possible for you too have it run under strace or truss we
might be able to figure out what signal causes the problem.

Probably it will also work to modify the following function in
g10/signal.c to read:

static const char *
get_signal_name( int signum )
{
#if defined(SYS_SIGLIST_DECLARED) && defined(NSIG)
    return (signum >= 0 && signum < NSIG) ? sys_siglist[signum] : "?";
#else
    /*return "some signal";*/
    static char buf[100];
    sprintf (buf, "signal no %d ", signum);
    return buf;
#endif
}

I'll do a release candidate for 1.2.6 today (unless your signal
problem is serious) including the patch.  This is also to test the new
gettext version we decided to use for 1.2.6.
