BT from gdb for the WebProcess

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:

"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"'

After visiting several pages, eventually, the WebProcess hits a Critical.

This bug is not reproducible in a predictable way.
