Google uses its own canonicalization rules to determine if domain.com is the same as www.domain.com. Sometimes for unknown reasons it makes an incorrect assumption and when Google makes an incorrect assumption anything can happen :)

To be fair this does not happen as often as it used to and with Yahoo it used to happen all the time.

If Google indexes both then there can be even more problems. For example unsolicited links can link to either and this is why it is not uncommon on older sites to see both versions with a PR and this is a waste of links.

You loose nothing by putting in a redirect and it prevents some potential spidering and indexing problems.

Sometimes no effect and other times I have seen sites completely buried in the SERPs until putting in a 301 redirect.
