I think it's a problem when you may have beliefs that some others don't agree with but which you don't think they they have a right to know.
Here's a simple case: What if your employer was very stuck-up and controlling and the CEO is a crazy {insert religion or lack of here}. They make you log in from home to check your email on their website. Now what if their website sniffed your computer to check if you'd been looking at {insert other religious belief here} and forwarded that information on.
In this case your expectation of privacy does not match the actual privacy case. Most people wouldn't think that looking at a hard-core christian website from home might get them looked at funny by their atheist bosses. This is a case of technology not behaving properly, which is a bug.
You can think of all sorts of cases where there might be negative consequences for you if everyone could view your at-home browsing history.
