fails to start inside chroot

[sascha_silbe]

I'm doing most of my development work and testing on my desktop inside a Debian Squeeze chroot. org.laptop.TurtleArtActivity fails to start inside the chroot because the dbus system bus is unavailable:

Traceback (most recent call last):

See  08b278a for how I fixed a similar issue in sugar.

This should be fixed in v107

Still happens:

You wrapped the bus.get_object() call in a try/except block, but not the dbus.SystemBus() call that failed. Both calls can throw a DBusException that needs to be caught.

The dbus call is no longer used in the code.
