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? Thank you all so much in advance!<div><br></div><div>- Erik<br><div><br></div><div><div style="background-color:rgb(250,250,250);border-color:rgb(187,187,187);border-style:solid;border-width:1px"><code><div><span style="color:rgb(0,0,0)"><div>#0 0x00007fffd2e90eea in ??
