I typed up what's below, but probably solved the problem: the default setting of URL in xscreensaver of "http://www.livejournal.com/stats/latest-rss.bml" seems to be the source of potentially offensive text. The solution is probably to run xscreensaver-demo, go to the advanced tab, and change the "text manipulation" setting to something like a blank filename, or "Host Name and Time" (or just use a different URL).

Can you invoke
Code:
/usr/libexec/xscreensaver/noseguy
directly and still see the problem text?
noseguy's default behavior is to call
Code:
xscreensaver-text --cols 40 | head -n15
which ought to output hostname-, uname-, date-, and w- type information. The command "xscreensaver-text", with no options, appears to have identical output to the above command on slackwares 12.2 and 13.
Are you using KDE4 or KDE3.5 or something else entirely?
From what I see of the KDEs' screen saver configurations, they don't seem to have ways of tweaking individual xscreensaver settings.
Are you running xscreensaver ? (pgrep xscreensaver to see)
In KDE 3.5, running "xscreensaver" directly and choosing "settings" without a running xscreensaver daemon will pop up a dialog box to complain about KDE's existing screen saver daemon.
Also, do you have an ~/.xscreensaver file ? xscreensaver-demo will write this file when it is run for the first time. xscreensaver-demo also has what appear to be master text source options (in your case, mastur-text

) for xscreensaver binaries.
If you do have this file, try grepping it for "noseguy" to see if it shows more options than just -root. The manpage for noseguy show it has several options regarding where it gets its text, the trick here seems to be isolating what is causing the problem.
