What version are you running? 1.5 What's the URL of the page containing the problem? http://reviews.reviewboard.org/admin/settings/general/ What steps will reproduce the problem? 1. Enter a relative path for "Search index file" 2. Save What is the expected output? What do you see instead? On PyLucene 2.x, a Java error will be thrown. On 3.x, an HTTP 500. This should be validating that the path is absolute and possibly that it exists and is writable (though we need to make sure we're not going to cause problems for installs that haven't yet run an index).
