If you find bugs, then you find bugs. Just make sure that the bug hasn't already been reported, and that it is actually a bug (not just you expecting something to behave differently - the unexpected behaviour may be intentional, or at least documented) Other than that, though; bugs are bugs, and waiting to submit them to spare a developer's feelings doesn't really help anyone.
