- build with
./configure --with-cairo --with-modules --with-xwidgets - run as
emacs -Q - execute from emacs
(xwidget-webkit-browse-url "file://~/some.html") - See backtrace
The backtrace linked above was from a native-comp build, but this is reproducible without it.
See https://github.com/masm11/emacs/issues/69 for relevant info and a possible fix to the null pointer.
