python crashes and completely freezes PC upon startup

I might should mention I'm currently running the 64-bit Kubuntu 8.04 beta on a Gateway NX860XL laptop (sorry about that).

That crash has nothing to do with the lock-up of your computer, sorry.

It is probably because the dbus has been restarted, that you received the above crash. I don't know if a dbus restarting can cause your computer to freeze (have never heard about that it could); but in any case you should try to look further at your logfiles and see if you can find the cause there.

It just happened again...

Looking in /var/crash revealed the same crash report as above, at the same time of the system freeze, but the logs don't reveal much. One thing I did notice was that most activity around the time of the crash was networking stuff; I opened KSystemLog and looked at everything around 14:12 (the time of the crash), copied it all to a .txt file, and looked for anything having to do with dbus. This is what I found:

Is it possible something funny's going on with NetworkManager?

Here's something kinda' interesting from my syslog (please bear with me, I'm still pretty new at this):
