Could not replicate this in testing. Your crashlog mentions Sophisticated Backpacks - if you have one on, you can try removing it from your inventory temporarily and see if that fixes it. Also, the crash log mentions PSI Contributor spell circles , and from a quick look it seems like this crash might only happen if you are a contributor. If the backpack doesn't fix it, then it's probably a PSI bug.
