If this is a GIO bug, I can refile at Gnome. Also, I'm not sure what version I should choose, this is QtWebkit's 2.2 release.

CCing Alexis Ryan, WebKitQt now uses the "pure" GStreamer MediaPlayer implementation. Can you please test it? I don't know if there's any release including it yet, it's a fairly recent move. If the crash still happens it'd be interesting to know the versions of: gstreamer-0.10 gst-plugins-base gst-plugins-good

QtWebKit 2.2 will also move to a pure GStreamer implementation without QtMultimedia. Could you checkout the 2.2 branch and test again. The patches are there now.

Maybe we can close this issue now unless it still happens?

We are now using gstreamer on Linux.
