[Digikam-users] P: digikam error under 'project neon'

[Markus Spring]

Not too happy with the current kde4 release, I installed the next kde's nightly
builds 'project neon' under kubuntu 8.10

While all the normal applications including digikam 9.3 from the repositories
work fine, digikam 10 from svn - which works under standard kde4 version -
starts but does not show any thumbnails. In the terminal window klauncher gives
the ominous message: Unknown protocol 'digikamalbums'.

kbuildsycoca did not bring any change, and I am running out of ideas.

Any hints how to resolve this?
