Application that crashed: kcmshell4
Version of the application: 
KDE Version: 4.2.85 (KDE 4.2.85 (KDE 4.3 Beta1))
Qt Version: 4.5.1
Operating System: Linux 2.6.28-12-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I added the kubuntu-ppa repository to the sources.list (via KPackageKit) and then ran Aptitude update && aptitude full-upgrade.

After running it several times, i managed to get the full-upgrade status to 1 packages upgraded, 3 not upgraded.

When i attempt to update the kde-icons-oxygen (version 4:4.2.85) package, it generates the following error:

dpkg: error processing /var/cache/apt/archives/kde-icons-oxygen_4%3a4.2.85-0ubuntu2~jaunty1~ppa2_all.deb (--unpack):
 trying to overwrite `/usr/share/icons/oxygen/16x16/status/meeting-organizer.png', which is also in package libkdepim4
dpkg-deb: subprocess paste killed by signal (Broken pipe)
Errors were encountered while processing:
 /var/cache/apt/archives/kde-icons-oxygen_4%3a4.2.85-0ubuntu2~jaunty1~ppa2_all.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)
A package failed to install.  Trying to recover:

And when i re-run the full-upgrade its status is still 1 packages upgraded (kde-icons-oxygen) and 3 packages not upgraded.

I then tried to update the kde-icons-oxygen package using software-updates and it crashed, generating this bug report.
