There is no "Okular 5". If you refers to an Okular version which used Frameworks 5 libraries, it does not exist either and it's not even in alpha state. The first version of Okular based on Frameworks 5 will be shipped not before the release of KDE Applications 15.08, so around August this year. Even the next version of KDE Applications, 15.04, will ship a kdelibs4-based version of Okular.

this repository keeps sending updates as okular5:
http://download.opensuse.org/repositories/KDE:/Unstable:/Extra/openSUSE_13.2/x86_64/?C=M;O=D
Were those packaged from the git?

All git snapshots. I would say that the repository name is misleading, it's not Unstable, it's more Experimental! I would personally call "Unstable" the git snapshots of the _next_ version, not the snapshot of a alpha branch. That's just not for Okular.

Stop using experimental software and reporting errors. You can either use supported software and report errors or use experimental software and contribute patches.

Wow, you sir again. A perfect demo of "With free stuff comes the 
attitude" :)

How are you making the world better?

let me think for a while...oh yes, by reporting bugs?

Reporting bugs is fine and nice for applications which are in a consumable state for an advanced user. The status of that code is really "touch this only if you can compile and debug it yourself", which means, as Albert pointed out, that people touching it are expected to provide patches and not bug report, right now. I don't agree with the choice of OpenSUSE packagers to provide an easy access to all of this code without this kind of warnings (if the warnings are there, that's a different story, still this is alpha code).
