Upstream: http://bugzilla.gnome.org/show_bug.cgi?id=337814 If gtk+-2.6.17 is installed, and any of the gestures, auto-scroller or push-scroller extensions are enabled, epiphany locks up the X server whenever the middle mouse button is clicked in a window. The fix is in epiphany-extensions-2.14.1, so I suggest bumping to that version. Alternatively, commits are: http://cvs.gnome.org/viewcvs/epiphany-extensions/extensions/auto-scroller/ephy-auto-scroller.c?r1=1.10&r2=1.11&makepatch=1&diff_format=u http://cvs.gnome.org/viewcvs/epiphany-extensions/extensions/gestures/ephy-gesture.c?r1=1.9&r2=1.10&makepatch=1&diff_format=u http://cvs.gnome.org/viewcvs/epiphany-extensions/extensions/push-scroller/ephy-push-scroller.c?r1=1.3&r2=1.4&makepatch=1&diff_format=u (Yes, gtk+-2.6.17 isn't in Portage yet. That's why I marked this major and not critical.)
2.14.1 is committed. Thanks.
