Hey,

I’ve just compiled ruby-gnome2 (from cvs) against xulrunner’s  
gtkmozembed library, and I’ve discovered that calling  
Gtk::MozEmbed.set\_profile\_path(“/usr/lib/firefox/plugins”) – before the  
constructor – causes some problem that prevents any page being loaded  
by the widget. Even if the path given to set\_comp\_path is an empty  
directory, it still doesn’t work. No errors are thrown.

I tried this on another machine with ruby-gnome2 compiled against  
mozilla-gtkmozembed and that throws a segmentation fault.

P.S. Below is a short snippet that will replicate this problem. Does  
anybody know what the problem is?

Regards,  
Andy.

#!/usr/bin/env ruby

require ‘gtkmozembed’

# Uncomment this line and no page will be loaded…

#Gtk::MozEmbed.set\_comp\_path(“/usr/lib/firefox/plugins”)  
Gtk::MozEmbed.set\_profile\_path(ENV[‘HOME’] + ‘/.mozilla’, ‘RubyGecko’)

win = Gtk::Window.new  
moz = Gtk::MozEmbed.new

win \<\< moz  
win.resize(780, 570)

puts “Trying…”  
moz.load\_url(“[http://www.google.com/](http://www.google.com/)”)

win.signal\_connect(“destroy”) { Gtk.main\_quit }

win.show\_all  
Gtk.main

The comp\_path is set at compile time following xulrunner settings, i  
think  
you should not call set\_comp\_path unless you have some good reason to do  
so.

Are you sure that using firefox comp\_path on a xulrunner compiled  
gtk\_moz\_embed is safe and can be done?
