Why would the circuit breaker short when a multilight lamp on the end of a run with a pull chain switch is turned on?

The cicuit braker should only trip when there is too much current running through it. Check to see what the braker is rated for (maybe 10 or 15 amps). Then take stock of what equipment is in that circuit (maybe a couple of lights?) and estimate how many amps the circuit should be drawing (maybe two or three). If there aren't a million lights plugged in to this circuit then chances are the light fixture in question is shorting out when you turn it on.

circuit breaker is a switch that turned off when there is a short circuitAnswerAn air circuit breaker is a high-voltage circuit breaker whose tripping and closing mechanisms are (usually) operated pneumatically, and whose arc is extinguished by a blast of air -hence the alternative name 'air-blast circuit breaker'.

Yes a circuit breaker is a switch but it should not be used as a switch. The continuous turning off and on of a breaker weakens the internal mechanism and reduces the tripping value of the breaker. There is in the marketplace breakers that are designed to be used as switches. These are usually used in large warehouses where the lights are turned on in the morning and shut off at night. Using these specifically designed breakers for switches does not wear out the tripping mechanism or reduce the tripping value. <<>> A circuit breaker can be used as a switch, although in most cases there are less expensive switches you can use.

To de-energize a circuit, the voltage has to be cut off at the source. This is usually done with a disconnect switch which is located just before the circuit's load. Turning off the breaker on a distribution panel will de-energize the circuit it is feeding. To make sure that the voltage can not be turned back on when work is being done on the circuit, the switch or breaker must have a lock off device to prevent the circuit from being turned on, except by the person that locked the circuit off.

Yes a bad circuit breaker and a bad light switch can cause a light to flicker when its turned on. It could also be caused by loose wiring going or coming from that paticular circuit. it also could be something in the fixture itself causing. Checking for loose connections is your cheapest and first route to go.
