No luck so far for me. I am trying to find one version that actually works with FC31 before starting the git bisecting process. I am now at 2.27.4 (no luck) and continuing to go further back (let's hope it would work with 2.26.4). 

Btw, I think this issue is also related to other components that are specific to FC32. I could verify that webkit2gtk3-2.28.0 + epiphany 3.34 runs perfectly on FC31.
