Appearantly harmless error in startup method

Classic Servoy

I’m getting this method when showing a splash screen (a fid with my logo):

18-dic-2006 18.43.38 com.servoy.j2db.util.Debug error
GRAVE: Throwable

It doesn’t seem to give any subsequent problem, but I’m wondering what can be causing it: I tried removing almost anything from the splash, without getting rid of it.

Any idea? :-)
