问题
I'm trying to embed a web browser into a gtk project. I'm trying to use WebKitGTK (but I'm not committed to it), every time I try and use it to parse an Ext JS page, it crashes the entire application. Here's the output, and how I'm including the .js files...

Any suggestions would be great, this is really my only roadblock left. Thanks!

This is an Ubuntu issue with the flash plugin I was using. Here's the stack trace.
