Usemin fails to update CSS file & JS file image paths correctly.

I am also having this issue. Gulp does not properly search the paths when running the gulp task.

The error "bootstrap.min.css" is not found is invalid, as the file is clearly in the directory when the gulp task is ran.

Gulp configuration file:

var gulp = require('gulp')
    , minifycss = require('gulp-minify-css')
    , jshint = require('gulp-jshint')
    , stylish = require('jshint-stylish')
    , uglify = require('gulp-uglify')
    , usemin = require('gulp-usemin')
    , imagemin = require('gulp-imagemin')
    , rename = require('gulp-rename')
    , concat = require('gulp-concat')
    , notify = require('gulp-notify')
    , cache = require('gulp-cache')
    , changed = require('gulp-changed')
    , rev = require('gulp-rev')
    , browserSync = require('browser-sync')
    , del = require('del');


var ngannotate = require('gulp-ng-annotate');
gulp.task('jshint', function () {
    return gulp.src('app/scripts/**/*.js').pipe(jshint()).pipe(jshint.reporter(stylish));
});
// Clean
gulp.task('clean', function () {
    return del(['dist']);
});
// Default task
gulp.task('default', ['clean'], function () {
    gulp.start('usemin', 'imagemin', 'copyfonts');
});
gulp.task('usemin',['jshint'], function () {
    return gulp.src('./app/**/*.html')
        .pipe(usemin({
            css:[minifycss(),rev()],
            js: [ngannotate(),uglify(),rev()]
        }))
        .pipe(gulp.dest('dist/'));
});
// Images
gulp.task('imagemin', function () {
    return del(['dist/images']), gulp.src('app/images/**/*').pipe(cache(imagemin({
        optimizationLevel: 3
        , progressive: true
        , interlaced: true
    }))).pipe(gulp.dest('dist/images')).pipe(notify({
        message: 'Images task complete'
    }));
});
gulp.task('copyfonts', ['clean'], function () {
    gulp.src('./bower_components/font-awesome/fonts/**/*.{ttf,woff,eof,svg}*').pipe(gulp.dest('./dist/fonts'));
    gulp.src('./bower_components/bootstrap/dist/fonts/**/*.{ttf,woff,eof,svg}*').pipe(gulp.dest('./dist/fonts'));
});
// Watch
gulp.task('watch', ['browser-sync'], function () {
    // Watch .js files
    gulp.watch('{app/scripts/**/*.js,app/styles/**/*.css,app/**/*.html}', ['usemin']);
    // Watch image files
    gulp.watch('app/images/**/*', ['imagemin']);
});
gulp.task('browser-sync', ['default'], function () {
    var files = [
        'app/**/*.html'
        , 'app/styles/**/*.css'
        , 'app/images/**/*.png'
        , 'app/scripts/**/*.js'
        , 'dist/**/*'
    ];
    browserSync.init(files, {
        server: {
            baseDir: "dist",
            index: "index.html"
        }
    });
    // Watch any files in dist/, reload on change
    gulp.watch(['dist/**']).on('change', browserSync.reload);
});

Error when running the gulp task in command line:
