>Description:
recent versions of GNOME 2 start programs with all signals blocked.  For terminal
	applications (gnome2-terminal, xterm, etc.) this is disastrous if the user's shell fails
	to reset the signal mask (e.g. /bin/sh); child processes cannot receive signals.
	
>How-To-Repeat:
	Log in with the GNOME desktop and a shell other than csh.

	Here's a program that reports the current signal mask.

#include <signal.h>

int main(void) {
	int i;
	sigset_t oset;
	sigprocmask(0, 0, &oset);
	for (i = 1; i < 16; ++i)
		printf("%d %d\n", i, sigismember(&oset, i));
}

	Here's its output under the broken combination (GNOME + non-csh shell):

1 1
2 1
3 1
4 1
5 1
6 1
7 1
8 1
9 0
10 1
11 1
12 1
13 1
14 1
15 1

	The correct output (if your shell is csh, or your not using
	the GNOME desktop) has `0' for all entries in the second
	column.

	
>Fix:
	
	Unfortunately not known: I'm not familiar enough with the
	architecture of GNOME to know where to look for this.
