[Bug 1300742] [NEW] dbus-monitor crashes whole system

[Markus Vuori]

Public bug reported:

I tried couple of commands:

dbus-monitor --profile "interface=org.gnome.Screensaver"

and

dbus-monitor --session
"type='signal',interface='org.gnome.ScreenSaver',member='ActiveChanged'"

Both of them cause a system crash within 5 - 20 seconds. I can't change
vt or log in via ssh. Mouse pointer does not move.

Once I managed to switch to vt1 before crash, and I managed to take a
photo.

Kernel version:
Linux litebook 3.13.0-19-generic #40-Ubuntu SMP Mon Mar 24 02:37:00 UTC 2014 i686 i686 i686 GNU/Linux

Ubuntu 14.04 Beta 2 (updated today) and dbus-1.6.18-0ubuntu3

dmidecode says this is a MacBookPro6,2   ( 8 GB RAM, 2 GB swap, no apps
running except gnome-terminal and normal ubuntu unity desktop)

I suppose the problem is due to excessive logging and/or forking?
