pylint crashes on default values of a custom constant type

[Vincent Povirk]

I'm getting the following exception when running pylint on my code:

Traceback (most recent call last):
  File "/usr/bin/pylint", line 3, in <module>

I have attached a small test case.

Thanks for reporting this issue and help making Ubuntu better.

I get the same error message when running pylint on your example file on Ubuntu Raring.

[sthenault (sylvain-thenault)]

this bug should be fixed by forthcoming logilab-astng release (0.24.3 or 0.25.0)

[Hans Joachim Desserud (hjd)]

Pylint 1.1.0-1 on Ubuntu 14.04 handles the example file without crashing. Thus, I'm marking this issue as fixed.
