Burnt bulb trips breaker

What could cause a burnt light bulb to trip the breaker. The fixture has 6 bulbs and twice this week when a bulb burnt, the breaker tripped.
Thanks

Sometimes when a lamp burns out a small piece of the filament will break off and short out the two internal wires that supply power to filament. This short piece of filament can have a low enough resistance to trip the breaker.

Thank you for your reply. I've been worried about fire. I took the fixture down and don't see any exposed wiring. The other bulbs have a black film at their base which new bulbs don't have.
