Why mozilla plugins and xulrunner being used by WebKitGTK?

Question

I've got a simple application using WebKitGTK 1.6.0 that simply displays a webpage in a window.

When I browse a page using it that contains an Ogg/Theora video and HTML5 video element it appears this simple application is using some mozilla plugins and even xulrunner. Can somebody tell me why this is?

Here is a list of files open by the program using lsof.

I built WebKitGTK 1.6.0 and most of it's dependencies from source including gstreamer-0.10 and the gstreamer plugins. No where do I recall configuring WebKitGTK to using any mozilla plugins or xulrunner.

What might be causing the mozilla plugins, libtotem and xulrunner to be loaded? I provided the link to the files the application is using in hopes that it might provide a clue.

Answer 1

Lol, found the reason. I have FireFox, totem and totem-mozplugin installed on my system. Once I removed totem and totem-mozplugin, WebKitGTK used the appropriate Gstreamer plugins to render the video and audio.
