Closing a tab in Epiphany makes WebKitGTK crash:

[340549.969001] epiphany[497780]: segfault at 0 ip 00007fe241add5cb sp 00007fff599bc3e8 error 4 in libwebkit2gtk-4.0.so.37.38.2[7fe241196000+2c31000]
[340549.969008] Code: c3 66 0f 1f 44 00 00 48 89 ee 4c 89 e7 ff d3 eb df 66 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 00 48 8b 47 28 48 8b b8 90 01 00 00 <48> 8b 07 48 8b 40 20 48 3b 05 cf 42 4d 02 75 05 31 c0 c3 66 90 ff

It happens at least with 2.25.3 and 2.25.4, only with the Wayland GTK backend (works on X11), only when using hardware acceleration.

My GPU: Intel HD Graphics 520 (Skylake GT2).
