This doesn't make much sense to me.. It should be linked to libdbus-1.so.3, and so it is on my system.
Could you please run LANG=C apt-get --reinstall install evolution/unstable ldd /usr/bin/evolution | grep dbus and provide output from both? If it doesn't make it better apt-cache policy evolution rm /var/cache/apt/archives/evolution_2.6.3-2_i386.deb LANG=C apt-get --reinstall install evolution/unstable ldd /usr/bin/evolution | grep dbus Also, it would be nice if someone else could confirm/disconfirm this report. /* Øystein */
