Errors and bugs are very much a different case. We appreciate screenshots for those, because they show us more clearly what's going on, and are very unlikely to be manipulated.

As Caed says, it's social issues on chat that are the main case where screenshots are a problem, when one person is trying to prove the bad bahavior of another. That's when we don't accept them as a matter of course
