This crash is likely caused by decoration and blur plugins calling wrapped functions from initWindow. I just pushed out some code that solves this by adding a new WindowAddNotify function that these plugins now hooks into. I'm pretty sure that this will fix your crash. Give the latest code a try and let me know.
