Hi

I have trouble running Gnome Root Terminal. Instead, an error dialog box appears:

Failed to run /usr/bin/gnome-terminal as user root.

Failed to communicate with gksu-run-helper.

Received:
f_file(258)] RETURN conv_err(19) -> -3 bad
[pam_handlers.c:_pam_parse_conf_file(258)] RETURN authtok_err(20) -> -3 bad
[pam_handlers.c:_pam_parse_conf_file(258)] RETURN authtok_recover_err(21) -> -3 bad
[pam_handlers.c:_pam_parse_conf_file(258)] RETURN
While expecting:
gksu: waiting

At meantime, another message appears in syslog:
localhost kernel: su[5559]: segfault at 0 ip b7df2473 sp bff7958c error 4 in libc-2.11.so[b7d7b000+14c000]

However, I have no problem running a user terminal and then su.

Any suggestions? Bu the way, I have gnome 2.26.3 on Gentoo Linux

Thanks in advance.

I don't quite understand how you are getting to this point. Are you logging into Gnome UI as root and then trying to launch a terminal window? This is what is sounds like. I thought by default they disallowed root logins to Gnome now. I haven't tried lately so I don't know.
Either way, I would look at pam because that appears to be where it is stemming from.

Digressing somewhat, I can't think why you would want to do this anyway.

Hi

In fact, I got this error since I recompiled pam with debug USE flag, 'cause I tried to find out why I wasn't able to reboot or shutdown my system every time I use Gnome Root Terminal (I was redirected to GDM instead) I even compiled hald DBus and ConsoleKit.I removes the debug flag on pam cause I suspect it is a ConsoleKit problem.Here are messages from syslog when using gksu gnome-terminal:

and here are other messages when I attempt to shutdown/reboot:
