[Python-projects] crash: pylint name_of_a_nonexisting_file

[V.Chukharev]

Hi,

pylint crashes if a wrong filename (a nonexisting file) is given:

$ pylint name_of_a_nonexisting_file
No config file found, using default configuration
Traceback (most recent call last):
  File "/usr/local/bin/pylint", line 4, in <module>
    lint.Run(sys.argv[1:])
  File "/usr/local/lib/python2.5/site-packages/pylint/lint.py", line 901, in __init__
    linter.check(args)
  File "/usr/local/lib/python2.5/site-packages/pylint/lint.py", line 457, in check
    filemods = self.expand_files(files_or_modules)
  File "/usr/local/lib/python2.5/site-packages/pylint/lint.py", line 527, in expand_files
    self.set_current_module(modname)
  File "/usr/local/lib/python2.5/site-packages/pylint/lint.py", line 552, in set_current_module
    self.stats['by_module'][modname] = {}
TypeError: 'NoneType' object is unsubscriptable
$ ls name_of_a_nonexisting_file
ls: name_of_a_nonexisting_file: No such file or directory

I think this should be considered as a bug, as something similar
to the message from ls is much easier to understand.

Thanks for a nice program!
