We would like to use Warnings plug-in instead of Violations plug-in as Warnings show the fixed and new PyLint warnings better. I tried to use PyLint parser after running this command but it fails:
pylint --rcfile=trunk/pylint/.pylintrc --output-format=parseable --reports=no --include-ids=yes `find . -name "*.py"` 2>&1 > pylint.log

This is the error:
[WARNINGS] Parsing warnings in files 'pylint.log' with parser PyLint

Is there a real bug in the PyLint parser or is my PyLint command incorrect for Warnings plug-in use? The same command works with Violantions plug-in.
