Both of these are more likely to be a bug in webkit or epiphany than in
glib or gtk.  For a next step, try setting the environment variable
G_SLICE=debug-blocks before running and see if you can get an abort()
closer to your bug.  If that doesn't work and you're feeling
adventurous, you can try some other things like compiling with
AddressSanitizer (-fsanitize) or running under valgrind.

The problem with memory corruption bugs is that the stack trace you've
provided only shows where the memory corruption was detected.  It
doesn't show where the memory corruption actually happened.
