24.2.50; Segfaults for xwidget-demo-basic |
|
Date: |
Sun, 28 Oct 2012 20:21:22 +0100 |
Package: emacs-xwidgets
I used the latest version of the emacs-xwidget branch.
What I did was:
M-X xwidget-webkit-browse-url
That worked. So I tried:
(load-library "xwidget-test")
(xwidget-demo-basic)
An empty buffer pops up and the segfault happens.
