[Digikam-users] Problem trying do install 2.3

[Markus Spring]

Hello list,
in the process of trying to upgrade to 2.3 ppa digikam, I am torturing 
my dpkg mechanisms on oneiric

Unpacking kipi-plugins-common (from 
.../kipi-plugins-common_2%3a2.1.1-0ubuntu1_all.deb) ...
dpkg: error processing 
/var/cache/apt/archives/kipi-plugins-common_2%3a2.1.1-0ubuntu1_all.deb 
(--unpack):
  trying to overwrite 
'/usr/share/doc/kde/HTML/en/kipi-plugins/acquire-savetargetpreview.png', 
which is also in package kipi-plugins2-doc 2:2.1.1-natty~ppa1
dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)
Errors were encountered while processing:
  /var/cache/apt/archives/kipi-plugins-common_2%3a2.1.1-0ubuntu1_all.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

is the action where I got stuck, and now I don't know how to fix that.

Any ideas will be greatly appreciated!

Markus
