TypeError: Cannot read property 'content' of undefined for "%" unit

[montgomery1944]

When using CSScomb 3.1.5 on LESS:

.test
{
    width: 100%;
}

I am getting exception:

I also have this bug.
But if use not default config, (ex. yandex.json, csscomb.json) all good.
Bug only in default (zen.json) config.

I also am having this issue on 3.1.5 on LESS. Running it through atom-csscomb. Looks to be related to the linked line number but a problem within the first method in gonzales-pe.

Having the same issue with LESS files here: kriasoft/react-starter-kit

Also when this error occurs the content of a LESS file is set to an empty string.

The bug was in Gonzales and it's already been fixed in latest version of the parser.
However I cannot update the package dependency because of compatibility issues.
So I've added a hotfix for this issue and released csscomb@3.1.6, please update.
