Thank you for the alert.

No registered maintainer for 'python3', so assigning to the Python group.

/usr/lib64/libpython3.7m.so is provided by lib64python3-devel and it is a development file so this issue come not from python3 but from gst-plugin-scan command.

Which package provides gst-plugin-scan?

I'm trying to figure out what's the pkg from where the issue is coming.

Do you have gstreamer1.0-python installed? Does the issue go away if gstreamer1.0-python is removed?

$ rm -rf $HOME/.cache/gstreamer-1.0/registry.x86_64.bin

Added a patch to fix hardcoded python3 shared library name.

Please test gstreamer1.0-python-1.16.0-1.1.mga7 from core/updates_testing. Test case is in comment 6.

$ rpm -qf $(which gst-inspect-1.0)
gstreamer1.0-tools-1.16.0-2.mga7

gstreamer1.0-tools is needed for the testing.

And make sure that lib(64)python3-devel is not installed.

Confirmed that now the fix works on my mga7 for x86_64:

Before:

$ LC_ALL=C.UTF-8 GST_DEBUG=2 gst-inspect-1.0 python

** (gst-plugin-scanner:31268): CRITICAL **: 15:06:37.914: Couldn't g_module_open libpython. Reason: /usr/lib64/libpython3.7m.so: cannot open shared object file: No such file or directory

$



After:

$ LC_ALL=C.UTF-8 GST_DEBUG=2 gst-inspect-1.0 python
Plugin Details:
  Name                     python

  Binary package           GStreamer GObject Introspection overrides for Python 
  Origin URL               http://gstreamer.freedesktop.org
$

after gstreamer install, removing my workaround symlink. login, 
journalctl | grep libpython did not show a problem
and above test procedure works as shown.

Used the QArepo tool to update to gstreamer1.0-python-1.16.0-1.1.mga7. No installation issues. 

Since David Geiger and Bit Twister both report that the issue is fixed, and I had a clean install, I'm giving this a 64-bit OK.
