fix IPython.embed...

fix IPython.embed without this change, IPython.embed throws the following traceback: File "explete.py", line 9, in dump_inputs IPython.embed() File "/home/pi/code/ipython/IPython/terminal/embed.py", line 287, in embed config = load_default_config() File "/home/pi/code/ipython/IPython/terminal/ipapp.py", line 379, in load_default_config for cf in Application._load_config_files("ipython_config", path=profile_dir): File "/home/pi/code/ipython/IPython/config/application.py", line 527, in _load_config_files log.debug("Loaded config file: %s", loader.full_filename) AttributeError: 'NoneType' object has no attribute 'debug' @Carreau was the last to poke around in this part of the code, so pinging him, just in case
