Browse should enable plugins

[manuq]

WebKitGTK+ settings [1] "enable-plugins" and "enable-java-applet" have default value TRUE, so plugins should work out of the box.

UPDATE: the following is false, see comment 4 below.

However, a simple test (attached) shows that this is not the case at least for the Python bindings. Plugins do not work by default, and setting "enable-plugins" to False makes Flash work. So this may be a bug in pygobject, inverting the booleans.

Gonzalo suggested csotts's preloading hack as a workaround. We can either add a workaround, or wait for WebKit2, as the fix is almost there for landing upstream.

Sorry previous comment was for #3411.

Also in Epiphany, if I uncheck "Enable plugins" in Preferences, only then I can see plugins.

Tested in F17 with webkitgtk3 1.8.0, and in F16 with webkitgtk3 1.6.1 .

Sorry, I've been fooled by the html5 video in youtube, the interface mimics flash quite good now. The hypothesis of the inverted functionality in "enable-plugins" should be dropped.

This piece of Python code will show the plugins that are available in the system for WebKit:

from gi.repository import WebKit
db = WebKit.WebPluginDatabase()
for p in db.get_plugins():
    print p.get_name(), p.get_path()
