I submitted a bug report to GStreamer about this issue. See https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/-/issues/1008. The GStreamer dev that helped out with my bug report found that the fault originates with libproxy in glib-networking. I ran the "environment-libproxy" test from glib-networking-tests and the result was: "$ /usr/libexec/installed-tests/glib-networking/environment-libproxy # random seed: R02S5b1dc0abfabd6b943121bee035468cde 1..3 # Start of proxy tests # Start of environment tests ok 1 /proxy/environment/uri ok 2 /proxy/environment/socks # child process (/proxy/environment/ignore [2067]) exit status: 1 (error) # child process (/proxy/environment/ignore [2067]) stdout: "" # child process (/proxy/environment/ignore [2067]) stderr: "**\nGLib-Net:ERROR:../proxy/tests/common.c:192:test_proxy_ignore_common: assertion failed (proxies[0] == ignore_tests[i].proxy): (\" http://localhost:8080\" == \"direct://\")\n" ** GLib-Net:ERROR:../proxy/tests/environment.c:72:test_proxy_ignore: child process (/proxy/environment/ignore [2067]) failed unexpectedly Bail out! GLib-Net:ERROR:../proxy/tests/environment.c:72:test_proxy_ignore: child process (/proxy/environment/ignore [2067]) failed unexpectedly Aborted"
The rest of the glib-networking tests complete without errors. I will submit a bug report for glib-networking.
