When selenium server returns an error status (HTTP status not 200), then the selenium client prints this error including backtrace to stdout. This is too verbose und I don't really understand, why is that necessary. As a developer I should be able to control it.
In case, that a developer rescues those errors in her tests (like I do), the error is rendered, which is confusing. Furthermore the whole test output gets unreadable.
