Why do rotten onions sometimes smell good?

Every so often I'll cut open an onion (usually ones I buy at an outdoor market) and the flesh inside will be soft and brown -- clearly rotten. This is usually just the first few inner layers.
But the weird, weird thing is, the rotten part smells very sweet and fragrant. Has anyone else experienced this, and can anyone explain what might be going on, on a biochemistry level, that transforms the smell of onions (which I love, but is nowhere close to being sweet) to something that smells like flowers or candy?
