Hello Roderich,
I looked a little around and found Debian bug #967941.
There the media file is a video file that led
to loading libopenblas.so. This seems to be caused
by the file gstreamer-1.0/libgstlibav.so.
I could reproduce it now within a VM with current testing.
By creating a mkv video container containing dummy h264 video.
This made tracker-extract crash with the same backtrace.
Details creating the test video file and some more
details in attached file.
Kind regards,
Bernhard
