BT from gdb for epiphany
Epiphany 3.22.5 and WebKit 2.15.4.
I'm running Epiphany with the dconf key:
"process-model" = "shared-secondary-process"
And the env variable:
The compilation was done with CMake args:
'-DENABLE_THREADED_COMPOSITOR=OFF -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"'
After visiting several pages, eventually, the WebProcess hits a Critical.
This bug is not reproducible in a predictable way.

Obviously, hits a Warning.

2nd similar BT from gdb
Probably, from the same warning chain.
(epiphany:22067): Gtk-WARNING **: Allocating size to GtkSocket 0x5555576b7930 without calling gtk_widget_get_preferred_width/height(). How does the code know the size to allocate?
This warning also happens with the inspector, that for sure we know how to allocate without calling gtk_widget_get_preferred_width/height(). Same with plugins, we give them the size that the web says they have, not what the widget wants. You can safely ignore this gtk+ warning.
I don't think this report is invalid. We should either fix GTK+ to not warn here, or find a way to work around the warning.
Up to you, I'm not going to spend any time on this.
