kde sometimes hangs during logout

Bug Description

Restart and shutdown always work, but when I try and just logout, it tends to hang with a blank screen and just the cursor. I have checked what processes are running from the console, but found nothing obvious that could be holding it up. The cursor that is shown is KDM's cursor, I know this because if you install the extra oxygen cursors KDM defaults to the black one and with my cursor set to the white one, it does make the switch to the black one when it hangs. On the occasion that it successfully brings up the KDM login screen, if you attempt to login it will go black after you enter your credentials and then re-display the KDM login screen. If you then re-enter your credentials, it will actually login. This occurs on 3 different computers I own, 2 laptops and 1 desktop. Two of the systems have AMD GPU's and are running the radeon driver, while the 3rd uses Intel graphics.

If there is any further information I can collect to help debug this or if this is actually an upstream KDE bug, I will be happy to submit any requested info.

I don't know if this is related but kdm logs this to syslog.

I noticed in the log for kdm after the greeter crashed (which is what I think is happening here) that there were errors about not being able to connect to a dbus instance (although I verified that dbus was running.)

I am getting this on fresh new installs of both Kubuntu 11.10 (release) and Kubuntu 12.04 alpha 2. I have reinstalled multiple times and I get this error on every logout.

There are similar sounding errors going back to 2008 (at least).
