It's usually caused by an unhandled exception.
You should be able to write it out by overwriting sys.excepthook
import sys
import traceback
def _excepthook(e,v,tb):
with open("error.log","w") as error_log:
error_log.write(str(e))
error_log.write(v)
error_log.write("Traceback:\n"+"".join(traceback.format_tb(tb)))
sys.excepthook= _excepthook
