I have two halogen bulbs on the same lighting circuit (240V - UK)
controlled by the same two switches, i.e, either switch will turn on
or turn off both lights. Recently one of the two bulbs died (open
circuit, as expected), causing the fuse / circuit breaker to trip.
Can anyone offer an explanation?

Pretty common. There are many theories why, but bulbs often short out on
failure. Many incorporate a fuse to try and prevent it taking out the
circuit. In the UK 'C' type circuit breakers are available which stand an
overload for longer before tripping. Might be useful if the light in
question is in a hallway where others will give at least some light if it
blows.
