However, after removing $HOME/.config/epiphany/session_state.xml I was
able to start again epiphany. It still gives me following errors at every start:

Warning: program compiled against libxml 209 using older 208
Illegal format hash table

(epiphany-browser:2477): GLib-GIO-WARNING **: Received property Created with type x does not match expected type t in the expected interface

And if I put original session_state.xml back there, it crashes again.
For privacy reasons I wanted to omit something from session_state.xml,
but with following minimalistic session_state.xml I can reproduce this
crash. The very relevant thing in XML seems to be 'loading="true"'.
