TypeError: Cannot read property 'height' of undefined

const gulp = require('gulp');
const spritesmith = require('gulp-spritesmith');
const gulpif = require('gulp-if');

gulp.task('sprites', () =>
  gulp.src('img/sprites/*.png')
      .pipe(spritesmith({
          imgName: 'sprite.png',
          styleName: 'sprite.css',
          imgPath: '../img/sprite.png',
          padding: 2
      }))
      .pipe(gulpif('*.png', gulp.dest('img/')))
      .pipe(gulpif('*.css', gulp.dest('_src/scss/vendor/')))
);

With bunch of random png files get the error message:
