Bug 315759 – [GStreamer][WebRTC] webrtc/getDisplayMedia-pc-resolution.html is flaky crashing

• Status: RESOLVED
• Resolution: FIXED
• Component: New Bugs

[Alejandro G. Castro]

This test (already marked [ Failure Timeout ] in glib/TestExpectations under
  webkit.org/b/314659) started crashing on the post-commit GTK/WPE bots, which
  correlates with assertions being enabled around r313986@main. wpe-release shows
  a sustained CRASH pattern since r313986.
