--- Comment #28 from Alexandre Demers alexandre.f.demers@gmail.com --- I'm closing this bug, the original triggering application is not doing it anymore. Also many things changed since then. I'll reopen it if for any reason I can still point to this exact problem, but I think it was more like an umbrella bug: many others were hidden under it.
