KPlato fails to start due to mimetype issue

[David D Short]

Binary package hint: kplato-kde4

I've just installed the latest kplato-kde4 from the repos, on Hardy Heron, and if I run it, I get this on the command line:

kplato(8764) KPlato::Documents::Documents: 0x817f7d8
kplato(8764) KPlato::Documents::Documents: 0x8190320
It seems your installation is broken/incomplete cause we failed to load the native mimetype "application/x-vnd.kde.kplato".

I see that this has been reported by someone to the KDE team (http://bugs.kde.org/show_bug.cgi?id=155906), but they blame it on Kubuntu.

I don't even particularly want to use KPlato, but since I'm forced to download it if I want Krita, I figure it might as well work.

Thanks.
