I haven't tried it with titlebar off, but here's a bug report I already
sent off to xbugs about utmpInhibit.

			  X Window System Bug Report
			    xbugs@expo.lcs.mit.edu


VERSION:
    R4

CLIENT MACHINE and OPERATING SYSTEM:
    VAX 8800 running Ultrix 3.0 (although bug applies to most BSD-style
    machines)

DISPLAY TYPE:
    Digital QVSS (on VAXstation 3100)

WINDOW MANAGER:
    not relevant (we're using twm and mwm though)

AREA:
    xterm

SYNOPSIS:
    Xterm will exit immediately (or core dump if run as root)
    if the "-ut" switch is set (or utmpInhibit is true) and it
    is running on any machine with BSD groups (HAS_BSD_GROUPS defined).

DESCRIPTION:
    If xterm is run on such a machine with -ut set, xterm will
    call "initgroups(pw->name, pw->gid)", but pw was not
    initialized, so initgroups dies.

REPEAT BY:
    Just run "xterm -ut" on such a machine.

SAMPLE FIX:
