Comment # 1 on bug 1040978 from Wolfgang Bauer

For reference, the actual problem as reported by zypper is this:
python-kde4-akonadi-4.14.3-5.14.x86_64 requires akonadi-runtime >= 1.13.0

I.e. python-kde4-akonadi is installed and won't get removed automatically.

This has been fixed in Factory over a year ago by dropping python-kde4-akonadi
and obsoleting it:

(it only makes sense with kdepim4 anyway)

I submitted python-kde4 from Factory to 42.3, that should solve the problem.
