I'm getting this error while compiling any styl file with the following context

/mnt/code/node_modules/gulp-sourcemaps/node_modules/through2/node_modules/readable-stream/lib/_stream_readable.js:623
var written = dest.write(chunk);

I disable gulp-sourcemaps and the error remains.

Please ignore Steve, I don't even want to write out the idiocy I am guilty of here :)

@stevelacy, I did read the message but this is a plugin that gulp itself depends on and both gulp-jade and gulp-coffee plugins work fine with it. Here is how I am invoking the plugin, that too with a single file.

gulp.task('stylus', function() {
gulp.src('www/*/.styl').pipe(stylus()).pipe(gulp.dest('www/'));
});
