How slow can brasero be?

I regularly try using brasero, only to cancel it or interrupt it a half-hour later when it still claims to be preparing files... normalizing them or something else. Mind you, when I stop it, it still hasn't even begun the actual burning process; the disc is untouched. What gives?

K3B, by comparison, starts actually burning my discs within 30 seconds at the absolute latest. Something is definitely wrong with brasero. Should I file a bug report? What information do I need to include? Is there a debugging varietal of brasero that would answer questions? Thank you for your attention to this.
