Theses lines were supposed to be topologically correct. They were generated in ArcInfo by another consultant... I just brought them back in ArcInfo and clean/build topology. The tiny gaps/imperfections were causing the problem... I should have tested/understood the disaggregate function better before bothering you.
Anyway, thanks to everybody. I'm still amazed by such cooperation. Have a nice week-end!
