Is NetworkManager running?
(In reply to comment #3)
> Is NetworkManager running?
This reply is from the running Live boot.
What I was seeing for this is that NetworkManager is running until I click Next in anaconda, then NetworkManager crashesd. It happened reliably a bunch of times, then didn't happen when I was running dbus-monitor to try and figure out what was going on. When it crashed with 'NetworkManager --no-daemon' the backtrace indicated it was a D-Bus exception triggered by the NetworkManager code trying to send an error message back.

Network Manager debug output
OK, so when I installed debuginfo packages, I was able to get a more informative output. Output from NetworkManager --no-daemon attached.
[ The crash of NetworkManager actually occurs when anaconda is started, it's only the anaconda crash that happens when you hit Next ]

Samsung N150 traceback
I also encountered this bug on my Samsung N150 netbook. The netbook uses a Realtek 8192E wireless card and a Ralink ethernet card. Traceback attached.

This is both a dbus-glib bug and an NM bug. We'll work around it in NM since NM's ifcfg-rh system settings plugin is doing something stupid to trigger this in dbus-glib.
For reference, the upstream dbus-glib bug is:
NetworkManager-0.8.0-7.git20100422.fc13 has been submitted as an update for Fedora 13.
NetworkManager-0.8.0-7.git20100422.fc13 has been pushed to the Fedora 13 stable repository. If problems still persist, please make note of it in this bug report.
