            Bug ID: 211166
           Summary: REGRESSION(r260814): [GTK]
                    webrtc/disable-encryption.html is a crashing flaky
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebRTC
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: dpino at igalia.com
                CC: youennf at gmail.com

The test has started to crash, most of the times, since r260814 (RTCPeerConnection should not remove its created remote MediaStream objects until getting close)

The failure is only reproducible when testing the whole 'LayoutTests/webrtc/' folder. If running the test alone, it passes. Likely the crash is due to a collateral effect with some other test in the same folder.

See: https://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20(Tests)/r260815%20(13522)/webrtc/disable-encryption-crash-log.txt
