Yes folks, after such a terrible delay we finally managed to get it correct. calligra 1:2.6.1-0ubuntu5 is now available in raring-release and it should now fully work. Sorry for such delay.
Report to us at kubuntu-devel@lists.ubuntu.com if you still have any problems after upgrading.
We will start backporting the release to Kubuntu 12.10 and Kubuntu 12.04.2 LTS in the Kubuntu Backports PPAs.
Much appreciated, looks good.
Thanks!
