[Murray Cumming <murrayc src gnome org>]

commit 5bb710d572794f075dce364313cc007503ff8061
Author: Murray Cumming <murrayc murrayc com>
Date:   Tue Aug 31 15:24:46 2010 +0200

    Catch Gnome::Gda::ConfigError exceptions.
    
    	* glom/libglom/connectionpool_backends/postgres.cc:
    	* glom/libglom/connectionpool_backends/sqlite.cc: Output to stderr when
      we get ConfigError exceptions. This is informative when the tests fail
      because of missing libgda providers. Note that this won't happen in the UI
      because we test for the providers at startup.
