BT from gdb for the UIProcess

I'm using WebKitGtk+ with my own JHBuild setting:
https://github.com/tanty/jhbuild-epiphany/tree/master

Epiphany 3.20.6 and WebKit 2.15.3

I'm running Epiphany with the dconf key:

"process-model" = "shared-secondary-process"

And the env variable:

"export LIBGL_DRI3_DISABLE=1"

The compilation was done with CMake args:

'-DPORT=GTK -DCMAKE_BUILD_TYPE=Release -DENABLE_MINIBROWSER=ON -DCMAKE_C_FLAGS_RELEASE="-O0 -g -DNDEBUG -DG_DEBUG=fatal-criticals -DG_DISABLE_CAST_CHECKS" -DCMAKE_CXX_FLAGS_RELEASE="-O0 -g -DNDEBUG -DG_DEBUG=fatal-criticals -DG_DISABLE_CAST_CHECKS"'

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

This bug is not reproducible in a predictable way.
Comment 1 Andres Gomez Garcia 2017-01-20 05:12:02 PST
I'm not adding this into bug 165656 since the X Error is different.

Also, this time it happened straight away, upon opening Epiphany.

This is the log spit in the UIProcess tab:

(epiphany:6367): GLib-GObject-CRITICAL **: g_object_unref: assertion 'G_IS_OBJECT (object)' failed
The program with pid 6367 received an X Window System error.
The error was 'RenderBadPicture (invalid Picture parameter)'.
