Search from the Reader does not open document
Search for a document from the Reader application, and tap to open it. This displays blank screen (even the app UI elements are not rendered).
Search from Spotlight does open and display the document correctly.
This is reproducible on latest iPhone and iPad and iOS 10.0.2.
Note that scrolling through the document list and opening a document does work.
