BT from gdb
I'm using WebKitGtk+ with my own JHBuild setting:
<a href="https://github.com/tanty/jhbuild-epiphany/tree/wkgtk-devel">https://github.com/tanty/jhbuild-epiphany/tree/wkgtk-devel</a>
Epiphany 3.18.0 and WebKit 2.10.3
I'm running Epiphany with the dconf key:
"process-model" = "shared-secondary-process"
When visiting several pages, eventually, epiphany crashes.
This bug is not reproducible in a predictable way but happens quite often.

It seems, the crash happens when hitting:
#1 0x00007ffff13d6471 in willEnterAcceleratedCompositingMode () at /opt/gnome-os/tanty/epiphany/checkout/webkitgtk-2.10.3/Source/WebKit2/UIProcess/DrawingAreaProxyImpl.cpp:213
213 ASSERT_ARG(backingStoreStateID, backingStoreStateID <= m_currentBackingStoreStateID);</pre>
