The log file looks fine, so it appears to be an xml parsing issue. You
could try to install
the libxerces-c-dev package (Depends on Xerces 3) and rebuild the RTT
(only the marshalling plugin should be
recompiled):

sudo apt-get install libxerces-c-dev
roscd rtt/build
make install

(do make clean in build dir if make install does not rebuild marshalling)

And then try to redo the example. In 2.3, we have upgraded the support
for Xerces 3, and the
intention was to not break Xerces 2. It could be that we did not succeed...

Cheers,
Peter

This warning is given if the 'transport' parameter of the ConnPolicy
(see example.xml) is zero.
This could only happen if the reading of the XML file went wrong.

could you provide us with this information:
* output of same command, but first do export ORO_LOGLEVEL=7
* Is libxerces*-dev installed ? Ie any version of the
libxerces/libxercesc development package ?
