Errors in dbus-glib example-server.c

[Gnaural]

Of the two example program-pairs in the dbus-glib-0.74
tarball found here:
http://www.freedesktop.org/wiki/Software/DBusBindings

, only one seems to work. 

Specifically, the example-server/example-client pair
appear broken. The example-server starts and waits
fine, but crashes when the example-client contacts it.

Here is the command line output from both programs:

example-server:
