I just did a fresh install of 3.4.b (Installer package on 64bit Ubuntu Linux Server) and get a PageNotFoundException when trying to access the Web Quick Start web app. This error appears any content I try to access (content of type ws:article, ws:indexPage or ws:image). Images can be accessed when using the URLs in the format /wcmqs/asset/GUID/filename.suffix. So I assume this has something to do with the section lookup mechanism. All the content is the out-of-the-box data imported by the WQS Share dashlet (i.e. ws:webasset, ws:parentSections and ws:ancestorSections are all present where needed). Any idea what could cause that error?
