In what circumstances, if at all, does an individual have a right – or even a duty – to seek to overthrow by violence the government of his or her country?

I think it is the duty for citizens to act against the government using non-violent methods. Even if the government was committing violent atrocities against its own people, the people should not respond back in a violent fashion. If the goal is to overthrow the government in hope for a better and more just system, it shouldn’t be built upon violence. By revolting back violently, it would just create more problems. There are so many international resources that can help those oppressed by national governments that it would be senseless not to utilize them. Ex. Rwanda 1994 Genocide: Paul Rusesabagina sheltered roughly a thousand people, saving the lives of many, until outside help was received.
