The [0] at the beginning of each line indicates there was a problem getting the runlevel. What does the runlevel command output? I've fixed a minor problem acquiring the runlevel if you came from the charging runlevel but it won't help with the crashing.

The "inf=1" after the select() means ASUI is not mapped or the screen is off so the select won't timeout and sleeps until X or dbus wakes it. This means it could be crashing in the dbus thread so I put up a new debug binary to log dbus signals and callbacks, could you run that and give me the output?
