Package: dbus-1
Version: 0.23.4-1
Severity: grave
Justification: renders package unusable

Running lshal as root runs fine.
Running lshal as user gives:
	lshal version 0.4.7
	libhal.c 644 : Error connecting to system bus: No reply within specified time
	error: hal_initialize failed

After this, hald still runs but dbus-daemon-1 is gone.

Here's what /usr/bin/dbus-daemon-1 --system --nofork says when I run
"lshal" as a non-privilged user:

	berlin: ~ 11# /usr/bin/dbus-daemon-1 --system --nofork
	Segmentation fault
	berlin: ~ 12#

This is the strace of the daemon crashing:

This might have been fixed by

    2003-04-23  Ulrich Drepper  <drepper@redhat.com>

        * grp/initgroups.c (getgrouplist): Don't copy too much into the
        user buffer if more groups are found than fit into it.

        * nis/nss_nis/nis-initgroups.c (_nss_nis_initgroups_dyn): Use
        extend_alloca.

or

    2005-03-29  Thorsten Kukuk  <kukuk@suse.de>

        [BZ #661]
        * grp/initgroups.c (internal_getgrouplist): Check if we have
        enough space before adding the primary group to the list.

or

    2003-06-27  Thorsten Kukuk  <kukuk@suse.de>

        * nis/nss_compat/compat-initgroups.c: Don't use our own NIS/NIS+
        functions, dlopen corresponding NSS module instead.

After gotom's ping, no one responded except someone reporting the same
bug with 2.3.2, and I suspect this is the sort of bug that would make
people unhappy enough to report it when they see it.  Closing.

Please reopen if it happens again.
