"News.com is reporting that Steve Irwin was killed in a freak accident while filming one of his well known documentaries. Surprisingly it wasn't a crocodile, it was a sting-ray."
Well truth be told it would've happened sonner or later. Oddly though

IANASE (... not a stingray expert), but according to this article: [potamotrygon.de]
Stingrays are generally non-aggressive and intelligent creatures. They have been called the "pussycat of the sea," and devotees of diving programs on educational TV are often treated to images of scuba divers hitching a ride with some of the larger forms. This is a precarious activity at best, however, since the stingray's spine is in a perfect position to inflict injury to a human pressed against their dorsum. And if frightened, roughly handled, or captured, they react quickly by using their tail to place the sting in close contact with the object of their discomfort. Stingrays cannot raise or lower their stings voluntarily. The wound they inflict comes from the arching forward flick of their muscular tail. Envenomation occurs when the tip of the spine penetrates the ray's integumentary sheath and lacerates the skin of the victim simultaneously.
Human injuries also occur during stingray capture, when people attempt to haul them into a boat. Another common scenario is for the victim, wading in shallow water, to accidentally step on a stingray buried just beneath the sand. In these instances, the ray flicks up its tail, usually lacerating the leg. Contrary to popular "nature documentaries," it is extremely hazardous to swim directly over, or in close proximity to, a stingray. A flick of the tail is apt to pierce a person's body, and a serious, even potentially fatal, situation is in the offing.
The same article goes on to say [potamotrygon.de]:
Stingray injury has two aspects: 1) immediate physical trauma from the powerful penetrating action of the spine, and 2) envenomation at the site of the wound with the contents of the ray's integumentary sheath. Although venom is not always deposited during a "sting incident," these two insults often work in dangerous synchrony.
Most traumatic injuries inflicted by rays occur to the lower limbs of bathers and boaters, and to the hands and arms of fisherman, hobbyists and other handlers. If a major blood vessel is lacerated, hemorrhage can occur and could even be fatal. There is at least one case in the literature of a victim whose femoral artery was pierced by the spine of a stingray; the victim bled to death. In about 5% of such injuries, the spine is broken off and remains in the wound, especially when the fish is pulled off the victim. Penetration of any part of the trunk (chest, abdomen, groin) is a serious medical emergency. Introduction of the ray's necrotizing venom directly into the body cavity of a person has been known to cause insidious necrotizing effects on the heart and other internal organs, and death is often inevitable.
