From an Indie perspective, what kinds of bugs do you put off until later?

Obviously game-breaking bugs that crash or infinitely drain resources from the machine or prevent the player from performing actions need to be fixed ASAP. My question is, at what point do you, "fuck it, I'll fix it later" and continue working on features?

I'm curious whether or not there's a common consensus as to what needs to get fixed and what can be done when you have some free bandwidth.
