Hello Bernhard, maintainers
Thanks for your help.
I'm attaching the result of the gdb command, and the result of the
coredumpctl command.
As you suggested, I have installed gstreamer1.0-plugins-bad, and after
that, I can confirm that kamoso runs well.
Note that together with gstreamer1.0-plugins-bad all these packages were
installed:
freepats gir1.2-gstreamer-1.0 gstreamer1.0-doc
gstreamer1.0-plugins-bad gstreamer1.0-plugins-bad-dbg
gstreamer1.0-plugins-bad-doc gstreamer1.0-plugins-base-doc libde265-0
libglib2.0-dev libglib2.0-doc libgstreamer1.0-dev libmjpegutils-2.1-0
libmms0 libmodplug1 libmpeg2encpp-2.1-0 libmplex2-2.1-0 libofa0
libpcre3-dev libpcre32-3 libpcrecpp0v5 libsbc1 libvo-aacenc0
libvo-amrwbenc0 libwildmidi-config libwildmidi2 libzbar0 zlib1g-dev
Hope that helps.
Kind regards,
