Comment # 1 on bug 982301 from Wolfgang Bauer

Well, the problem is that kmymoney is (still) a KDE4 application and
uses/requires Akonadi4 (akonadi-runtime).

But Akonadi4 (akonadi-runtime) is not co-installable with Akonadi5
(akonadi-server), and KDE4 applications cannot just use Akonadi5 either.

Unfortunately it's also not possible to build kmymoney without Akonadi/KDEPIM
support.

Though AFAICT it only needs libakonadiprotocolinternals1 to run (the akonadi
server is only needed if you actually want to use the Akonadi functions), so we
could maybe change the dependencies for Tumbleweed, this can be installed fine
alongside Akonadi5. Of course the Akonadi functionality will not work without
akonadi-runtime, but at least you can start and use kmymoney.
I think the only function that needs Akonadi is fetching the personal details
from the addressbook, not really crucial I'd say.

I created a package with this change, can you please test it?

You could also try the (still unreleased) KF5 based kmymoney5 which will use
KDEPIM5. A package is available here:

But this is a development snapshot, it will only be available in Tumbleweed
when it has actually been released.
