Created attachment 302121 [details] BT from gdb for the WebProcess Epiphany 3.22.5 and WebKit 2.15.4. I'm running Epiphany with the env variable: "export G_DEBUG=fatal-criticals" The compilation was done with CMake args: '-DPORT=GTK -DCMAKE_BUILD_TYPE=Release -DENABLE_MINIBROWSER=ON -DCMAKE_C_FLAGS_RELEASE="-O0 -g -DNDEBUG -DG_DISABLE_CAST_CHECKS" -DCMAKE_CXX_FLAGS_RELEASE="-O0 -g -DNDEBUG -DG_DISABLE_CAST_CHECKS"' When visiting: https://www.spreaker.com/user/radiocable The WebProcess hits a Critical.
BTW, gstreamer-1.8.0
By the way, this is causing stderr output in dozens of layout tests. *** This bug has been marked as a duplicate of bug 167016 ***
