I've searched the list archives as well as a general google search but can find no references to this problem. My 10.1 installation recently started failing to start the dbus-daemon with a segmentation fault on boot. Checking status shows it running but it is dead, and gnome power manager refuses to start, giving a warning message when logging in to the desktop. Attempting a restart just indicates a segfault again.

Hi, Unfortunately my today's update to KDE 3.5.6 got me surprised with something: d-bus daemon fails to start due to segmentation fault.

Nothing appears in the /var/log/messages log.

First I noticed that my unmounted optical drives icons appeared on the desktop, which they previously did, only when a medium is inserted.

Then I got some messages about HAL being needed to mount those. So why wasn't hal running - answer - dbus could not start.

I wish, I saved my update log... Anyway, I am pretty sure that the update was only on the normal kde stuff - all the kde* packages, qt, arts and some other that usually get updated upon new KDE release.

Reinstalling dbus-1 or the kde 3.5.6 packages showed no results.

Any ideas?

After some debugging the problem revealed itself.

This was caused by this bug in dbus-userdb.c sourse file:

http://lists.freedesktop.org/archives/dbus/2006-February/004278.html

An infinite recursion is caused by having some group name in the config files that does not actually exists on the system. In my case this seemed to be 'netdev', mentioned in avahi-dbus.conf. This file has been created two days ago, during my previous update.

The quick workaround is to create a dummy group 'netdev'.

Maybe SuSE should release a patched version of dbus?

Thanks, that did the trick. Curious that my searches both on opensuse lists and a general google failed to find that, I guess it's too new to get indexed. Thanks again. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
