How to open Composite Document File V2 Document, Cannot read section info

Output of *file* command for a given odt file gives me Composite Document File V2 Document, Cannot read section info. By searching on Google I found it a doc document and I installed *unoconv* to read it on linux(fedora). But when I run the command: unoconv -d document --format=odt file.doc I get the following error: unoconv: RuntimeException during import phase:Office probably died. Unsupported URL Thumb.doc: "type detection failed"**. I am having all packages of libreoffice writer. So how do I open these kind of files on fedora?
