That was from Landry and is on the wiki[0].

Lidiriel, as I understand you are also looking for debug output.  Run
xfce4-panel in a terminal, and all plugins that have debugging support
will print their output there.

--enable-debug will output DBG, and --enable-debug=full will output
TRACE furthermore.  You will need to include config.h and libxfce4util.
Here is an example:

#ifdef HAVE_CONFIG_H
#include <config.h>
#endif
#include <libxfce4util/libxfce4util.h>

Note that you don't have to use these macros, but instead can rely on
g_debug[1].
