Package: pylint
Version: 0.19.0-1
Severity: normal
If I run pylint on the following program:
from matplotlib.figure import Figure
Figure().add_subplot(111).xaxis
...pylint never exits. It prints the following:
$ pylint generate.py
No config file found, using default configuration
************* Module generate
C: 1: Missing docstring
...and hangs, using 100% of CPU.
For the record, I'm using these versions of matplotlib:
ii python-matplotlib 0.99.1.2-2 Python
based plotting system in a style similar to Matlab
ii python-matplotlib-data 0.99.1.2-2 Python
based plotting system (data package)
ii python-matplotlib-doc 0.99.1.2-2 Python
based plotting system (documentation package)
If I interrupt pylab, it prints a very long stack trace which ends in:

If I try the same program on a machine running 0.18.1-1, it works without
incident, printing the following:
