I haven't been able to get konsole started for a few days. When I try to start it from the kde menu, it just creates a tiny transparent window which almost immeadiately disappears. So I started xterm to see possible error messages when I start it from there. First it shows this: KCrash: Application 'konsole' crashing... Invalid read from eventfd: Bad file descriptor Code should not be reached at pulsecore/fdsem.c:157, function flush(). Aborting. Unable to start Dr. Konqi Re-raising signal for core dump handling. Aborted (luotiin core-tiedosto) When I tried again, it showed this: ERROR: Caught a segmentation fault while loading plugin file: /usr/lib64/gstreamer-1.0/libgsttypefindfunctions.so Please either: - remove it and restart. - run with --gst-disable-segtrap --gst-disable-registry-fork and debug.

KCrash: Attempting to start /usr/libexec/drkonqi from kdeinit sock_file=/run/user/500/kdeinit5__0 It said it created a core file, but I can't find one from my home directory or /tmp. I wonder what it tries to do with gstreamer.. $ grep konsole /var/log/rpmpkgs konsole5-16.12.2-1.fc25.x86_64.rpm konsole5-part-16.12.2-1.fc25.x86_64.rpm konsole-part-4.14.3-11.fc24.x86_64.rpm $ grep gstreamer /var/log/rpmpkgs gstreamer-0.10.36-15.fc25.x86_64.rpm gstreamer1-1.10.4-1.fc25.x86_64.rpm gstreamer1-plugins-bad-free-1.10.4-1.fc25.x86_64.rpm gstreamer1-plugins-bad-free-gtk-1.10.4-1.fc25.x86_64.rpm gstreamer1-plugins-base-1.10.4-1.fc25.x86_64.rpm gstreamer1-plugins-good-1.10.4-1.fc25.x86_64.rpm gstreamer1-rtsp-server-1.10.4-1.fc25.x86_64.rpm gstreamer-ffmpeg-0.10.13-16.fc25.x86_64.rpm gstreamer-plugins-bad-0.10.23-7.fc24.x86_64.rpm gstreamer-plugins-bad-free-0.10.23-35.fc25.x86_64.rpm gstreamer-plugins-base-0.10.36-15.fc25.x86_64.rpm gstreamer-plugins-good-0.10.31-17.fc25.x86_64.rpm gstreamer-plugins-ugly-0.10.19-19.fc24.x86_64.rpm gstreamer-python-0.10.22-11.fc25.x86_64.rpm gstreamer-rtsp-0.10.8-12.fc25.x86_64.rpm gstreamer-tools-0.10.36-15.fc25.x86_64.rpm libnice-gstreamer1-0.1.13-7.fc25.x86_64.rpm PackageKit-gstreamer-plugin-1.1.5-1.fc25.x86_64.rpm phonon-backend-gstreamer-4.9.0-1.fc25.x86_64.rpm phonon-qt5-backend-gstreamer-4.9.0-1.fc25.x86_64.rpm qt-gstreamer-1.2.0-11.fc25.x86_64.rpm
It just occurred to me to try "su -c konsole" from xterm. After entering root password it displayed QStandardPaths: wrong ownership on runtime directory /run/user/500, 500 instead of 0 and started konsole as root. Of course, it still should be runnable as a normal user..
This problem seems fixed now. No idea what was going on, but now I was able to start konsole as a normal user again. Apparently some update has fixed it.
I have the same problem after upgrading to KDE 16.12.3 on gentoo. konsole works as root, as user i get a segementation fault while loading /usr/lib64/gstreamer-1.0/libgsttypefindfunctions.so. Did you upgrade to a newer version to fix this?

Some package update fixed it in April, over a month after the problem started. I still don't know which package was the actual culprit and which update fixed it, but I didn't update the whole distributon in betweem, I used Fedora 25 all that time. And didn't find any settings that would have fixed it.
... after some updates today the bug was fixed on my system, too. Some KDE packages got updated to 17.07.3 in the process, especially konsole, so i guess this update is responsible for fixing the bug for me: kde-apps/konsole-17.04.3.
