This is a small packaging problem. To get rid of the error you can safely remove libreoffice-emailmerge with dpkg (it is a transitional package, which means that it contains nothing, as it is now integrated in libreoffice-common package).
After this, reinstall libreoffice-common with synaptic or apt-get, everything should run fine. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/1160533 Title: The error occured short (1-2 Min.) after booting, I did not run libreoffice at all.
