[New-bugs-announce] [issue15377] os.path.join() error misleading with path1=None

[Chris Jerdonek]

New submission from Chris Jerdonek <chris.jerdonek at gmail.com>:

The error message for os.path.join() is misleading when the first argument is None.  The message should probably say something about mixing "None" and strings.

Python 3.3.0b1 (default:f954ee489896, Jul 16 2012, 22:42:29) 
[GCC 4.2.1 Compatible Apple Clang 3.1 (tags/Apple/clang-318.0.58)] on darwin
>>> import os
>>> os.path.join(None, 'a')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File ".../cpython/Lib/posixpath.py", line 89, in join
    "components.") from None
TypeError: Can't mix strings and bytes in path components.
