Latest update reports version as `1.5.0` causes pylint to crash:

Also affects pylama

Why was the summary changed to `[python-pylint]`? This issue affects `python-astroid` and only indirectly `python-pylint`. ABS commit `5826514450184bbd56cc37006e1eb68ea4d787db` changed from using a git tag to using a git commit. The upstream commit is after the version string was changed to `1.5.0`, making it incompatible with all applications relying on `<= 1.4.9`.

@nfnty That bump was needed for Python 3.6 compatibility, though. This has been fixed in pylint by bumping it to a later version, too.

@languitar It's not in the official repos. Please report this to the AUR package maintainer.
