Crash when using Broadway

[Pierre Rudloff]

Midori crashes when I try to use Broadway:

WebkitGTK currently makes unguarded calls to X11 functions, which fail under non-X11 GDK backends. I'm not 100% sure that's exactly what's happening here, but it's what happens for me after following the same steps. You might look at <https://bugs.webkit.org/show_bug.cgi?id=81456>.

It looks like an already-fixed issue with GError overlaps with the broadway-specific issues coming from WebKit.

With git master, I don't reproduce the GError issues, but something like:

(midori4:7191): Gdk-WARNING **: /build/buildd/gtk+3.0-3.6.0/./gdk/x11/gdkwindow-x11.c:4949 drawable is not a native X11 window

Program received signal SIGSEGV, Segmentation fault.

Incidentally tried with ppa:malizor/gtk-broadway on Ubuntu 12.10.

OP, can you confirm this issue still persists with the latest version of Midori and WebKitGtk? If so, can you post the information from about:version here?
