I am totally at a loss and I hope someone can help me. I've got a Gtk application running on Ubuntu that uses osgGtk to display the scene. The crash does not happen every time I do the same operation, only sometimes. As you can see, the crash is in libosg. I guess that I'm doing something wrong in an Osg call somewhere and the crash is just happening asynchronously? Either way I have absolutely no idea how to approach fixing this crash. Please help me! Here's a typical backtrace. Does anyone have any ideas?
