Thanks for taking your time to report this issue and help making Ubuntu better.
Could you elaborate a bit on how this bug occured, did it happen during upgrades or when installing new packages? The reason I'm asking is that it looks like the file in question (/usr/lib/x86_64-linux- gnu/qt5/plugins/libpmdummybackendplugin.so) is in both libkpmcore4 [1] and an older version of partitionmanager [2]. But it looks like the file has been removed (moved here?) from newer versions of partitionmanager [3]. So if it happens during upgrade, it might be that libkpmcore4 is added before partitionmanager has been upgraded to the newer version... >When I take a look at url (https://launchpad.net/ubuntu/+source/kpmcore/2.2.1-2), I see stories about unstable packages. In Debian, new packages are uploaded to "unstable" before they move to "testing" and eventually "stable". Development verisons of Ubuntu mainly sync from Debian unstable, so maybe that is what you're seeing.
