Every several hours, my terminal session is hit with hundreds of lines starting with kbuildsycoca4(10461).

An example line is kbuildsycoca4(10461) KBuildServiceFactory::populateServiceTypes: "phononbackends/gstreamer.desktop" specifies undefined mimetype/servicetype "video/anim"

This started happening yesterday when I installed konqueror from the Ubuntu Software Center. However, I've since removed konqueror and the issue persists.

What is causing this and how can I remove the nuisance?

According to this, you may be able to disable it with:

Hmm, any and each of these may be enough. In order of neatness and effort needed;

A. Start kdebugdialog and tick Disable all debug output.

B. Open up that ~/.local/share/applications/mimeapps.list, look for lines including mplayer.desktop and redact it or remove the entire section including it.

C. Start your programs with dolphin &>/dev/null. Or to fork and disown it; dolphin &>/dev/null & disown $!. Annoying workaround though.

With C, dolphin > /dev/null 2>&1 & disown may be better though.

The problem is probably caused by the kbuildsycoca4 executable, which is provided by the kdelibs-bin or kdelibs5-dbg packages, which were likely installed as a dependency of konqueror. So you may be able to fix your issue with one of these commands:

sudo apt-get remove kdelibs5-dbg
sudo apt-get remove kdelibs-bin

Note if you want other KDE apps they may be removed as well.

  • Did that. Now I'm getting /org/freedesktop/UDisks2 ... spillover. I searched dpkg --list | grep kde, and a number of packages show. Is that the best way to find out which dependencies remain?

  • @cfye14 - to remove all the kde pacakges it may be best to use a package manager like Synaptic then, as you can easily select all the packages and remove them. What new errors are you getting?

  • Continuing to get errors like this: "/org/freedesktop/UDisks2/block_devices/sdb" lost interfaces: ("org.freedesktop.UDisks2.PartitionTable") ... they all have that form, more or less
