Error processing a template

[stuartf]

When running grunt inlineImg I get this output:

Running "inlineImg" task
<WARN> An error occurred while processing a template (Cannot call method 'indexOf' of undefined). Use --force to continue. </WARN>

Aborted due to warnings.

My config for that task just looks like:

inlineImg: {
  shared: {
    src: [ 'shared/**/*.css' ],
    dest: 'target/optimized/shared/',
    ie8: true,
    base: __dirname
  }
}

So I don't think I'm introducing any templates, but I'm unable to find any in the grunt-imagine source either, so now I'm confused.

I patched grunt to make it dump a stack trace on template errors (https://github.com/gruntjs/grunt/pull/533) and got out this:

TypeError: Cannot call method 'indexOf' of undefined

Which seems to be a problem with grunt.file.expandFiles(config.src).

And now I see the problem with my config, this isn't a multi-task :hurtrealbad:

You can try the bleeding edge master branch from github, you can then use the multi-task feature.
