I get this too! It's not too sensitive to Eclipse version, as several versions have done this for me. It is sensitive to GTK version, as this only happens on one machine for me.
I did a little research on this when I first saw it, and the message is coming from the GTK2 libs. It's (obviously) a debug print left in by accident. On my offending machine, rpm -q reports
gtk2-2.0.6.0.200209120107-0.snap.ximian.1
gtk2-devel-2.0.6.0.200209120107-0.snap.ximian.1
i.e., a snapshot. No wonder it has extra messages in it.
Anyway, it's not harmful, as far as I can tell. If it really bothers you, try to upgrade GTK2. One of these days I'll get around to doing that myself.
