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

Epiphany 3.18.0, WebKit 2.11.90 and GStreamer 1.4.4

I'm running Epiphany with the dconf key:

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

The compilation was done with CMake args:

'-DPORT=GTK -DCMAKE_BUILD_TYPE=Release -DENABLE_MINIBROWSER=ON -DCMAKE_C_FLAGS_RELEASE="-O0 -g1 -DNDEBUG -DG_DISABLE_CAST_CHECKS" -DCMAKE_CXX_FLAGS_RELEASE="-O0 -g1 -DNDEBUG -DNDEBUG -DG_DISABLE_CAST_CHECKS"'

The WebProcess SIGSEVs

[Andres Gomez Garcia]

This is printed in epiphany's output:

(WebKitWebProcess:12206): GStreamer-CRITICAL **:
Trying to dispose element appsrc1, but it is in READY instead of the NULL state.
You need to explicitly set elements to the NULL state before
dropping the final reference, to allow them to clean up.
This problem may also be caused by a refcounting bug in the
application or some element.

I think I've seen this in the debug bot

[Philippe Normand]

Please update to GStreamer 1.6.3. This is what the bots use now.

But certainly WebKitGTK+ shouldn't crash with older versions?

[Philippe Normand]

This is one of the many duplicates reported about adaptive streaming issues with GStreamer 1.4.x :(

I think we should not recommend to our users versions below 1.6.x. We don't have the man power to support more than one stable GStreamer version.
