Hi Bert I know quite a few people (including me) who ran into the same, pretty anoying, problem.
And in general it is a known issue. See: http://hub.qgis.org/issues/2921 Did I understand you correctly that you already tried the workaround Marco suggests at the end of the ticket? This would indicate that activating topological editing is not enough (at least not in QGIS 1.8)... Did you also try activating snapping on lines and nodes as well? >From my personal point of view this issue is a mayor obstacle of using QGIS for digitising (though the digitising functions otherwise are really good and handy). I would really love to see a propper fix for that and that digitizing can not silently end up in incorrect results. At least you could clean your already digitised and incorrect data using GRASS and the topological vector format there...
