[IPython-user] Return to editor broken?

[Walter Dörwald]

Hi list,

It seems that the new "Return to editor" functionality kicks in even it 
the code wasn't edited in the editor:

If I type eval("?") I get a "Return to editor to correct syntax error? 
[Y/n]" prompt, if I type "y" here, I get an empty editor. Closing the 
editor without saving gives me the following stacktrace:

/usr/local/lib/python2.4/site-packages/IPython/iplib.py in 
safe_execfile(self, fname, *where, **kw)
    2064
    2065     def safe_execfile(self,fname,*where,**kw):
-> 2066         fname = os.path.expanduser(fname)
    2067
    2068         # find things also in current directory

/usr/local/lib/python2.4/posixpath.py in expanduser(path)
     311     """Expand ~ and ~user constructions.  If user or $HOME is 
unknown,
     312     do nothing."""
--> 313     if not path.startswith('~'):
     314         return path
     315     i = path.find('/', 1)

AttributeError: 'NoneType' object has no attribute 'startswith'
