A flickering light could be caused by one of several issues in the electrical system. Assuming the track is 100% okay, it could be the way the fixture is mounted. It must make solid contact with the electrical rails in the track. The contacts must be good. Are they clean and solid? Is the wiring in the fixture okay? All the way from the track pickups to the socket? Is the wiring at the socket solidly connected to the socket itself? Is the socket clean and in good shape? How about the lamp contacts? Are they clean and in good shape? Bayonet-mounted lamps with two "pins" that push into spring-loaded socket contacts can become oxidized and become intermittant. Sockets are the most vulnerable point in the circuit outside the lamp filament, which can just "burn out" as we all know. And when in doubt, replace the lamp and see what's up. If you've done that and it still flickers, the socket (first place) and the track contacts (second place) are the next places to look for trouble.

Can a bad lighting fixture cause a light bulb to fail?
If you install a bulb and it immediately fails with a flash then the fixture or more likely the supply voltage is a problem. This is a rare failure mode for the standard screw-in incandescent bulb. Essentially the only way it can happen is if a voltage in access of the rated voltage is applied to the bulb. It is more likely that the fixture shorts out and takes the bulb with it during the current surge. This can happen more easily than a constant over voltage condition, but after that the fixture is usually toast. If there is a ballast built in to the fixture, it can fail in a way that can eat light bulbs. One other failure mode that can reduce life of bulb is an enclosed fixture that overheats and causes the bulb to have a reduced life span.
