write after end

I did a recent update to libsass and this is the error that I keep getting: [gulp-sass] write after end

After some reading around, it seems to be a common error in some other packages. My css is still being built just fine.

Here is a bit more detailed error:

[13:21:07] Starting 'sass'...

events.js:72
        throw er; // Unhandled 'error' event
              ^

Here is my task:

var gulp         = require('gulp'),
    sass         = require('gulp-sass'),
    sourcemaps   = require('gulp-sourcemaps'),
    gulpFilter   = require('gulp-filter'),
    handleErrors = require('../util/handleErrors'),
    config       = require('../config'),
    autoprefixer = require('gulp-autoprefixer'),
    livereload   = require('gulp-livereload'),
    globbing     = require('gulp-css-globbing');

gulp.task('sass', function () {
  return gulp.src(config.sass.src)
    .pipe(sourcemaps.init())
    .pipe(globbing(config.sass.globbing))
    .pipe(sass(config.sass.settings))
    .on('error', sass.logError)
    .pipe(sourcemaps.write())
    .pipe(autoprefixer(config.autoprefixer))
    .pipe(gulp.dest(config.sass.dest))
    .pipe(livereload());
  return gulp.src(config.sass.src);
});

It did took some time to make this and to test so here is repository: https://github.com/macmladen/globbing-test

Explanations are in the root in README.md file.

There are four branches with different outcomes:

• master — fails, it has all of three things that breaks with Error: write after end
• gulp-glob — passes if only gulp globbing is turned off for directories
• css-glob — passes if we use gulp globbing but not gulp-css-globbing
• mixin-in-scss — both globbing there but no mixins in imported partials

If I can do anything to help, feel free to ask.

I am unable to reproduce this with v2.3.1. If the issue persists with latest gulp-sass please open an update issue.
