Description Jukka Lahtinen 2017-03-10 16:44:10 UTC

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: Application 'konsole' crashing...
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..

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.

Comment 5 Julian Kalinowski 2017-08-27 19:18:20 UTC

... 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.
