I tried viewing a fictionbook from http://manybooks.net/titles/vernejul3351633516-8.html with okular. Choosing download for the FictionBook2, I get a dialog which tells me it is of mimetype: application/x-fictionbook And gives the options to save it or choose an application to open it with. Choosing okular there works fine. The other way downloading it and trying to open it locally also works. There it even launches okular directly. But locally it says it has the Mimetype: application/x-fictionbook-xml. Please note the additional "xml". IMHO it would be nice if the other mimetype which is reported when trying to open it directly would also be supported. I initially reported this bug against okular at https://bugs.kde.org/show_bug.cgi?id=262696 and was redirected to report it here.
No, this is an okular issue, I will followup on the BR.
Sorry for the little messup: the actual problem is the lack of an alias, as reported by some servers.
Fixed, will be in the next release after 0.90.
