After some testing, I changed the following code in project_gtd.py, as suggested in the above mentioned forum topic and by Paulius :
search_extended +='''<separator orientation="vertical"/>''' # res['arch'] = res['arch'].replace('<separator name="gtdsep"/>', search_extended) res['arch'] = unicode(res['arch'], 'utf-8').replace('<separator name="gtdsep"/>', search_extended)
... and it works, but I don't know why ;-)
