Post-processing Failed

I recently upgraded both pipeline and Django to 1.11, and now I'm unable to run collectstatic. When I do, it pipeline seems to choke on arbitrary JS or CSS files. For example:

Fatal error: local() encountered an error (return code 1) while executing 'python manage.py collectstatic --noinput --traceback'

In the previous version, it was able to parse jquery-ui.min.css just fine, and the image ui-bg_highlight-soft_75_cccccc_1x100.png definitely exists at the path specified, so I'm not sure what's going on here.

My PIPELINE settings haven't changed, so I'm not sure what would be causing this other than the upgrade. My settings are:

PIPELINE = {
    'PIPELINE_ENABLED': True,
    'JAVASCRIPT': { ... },
    'STYLESHEETS': { ... },
    'JS_COMPRESSOR': 'pipeline.compressors.slimit.SlimItCompressor',
    'CSS_COMPRESSOR': 'pipeline.compressors.yui.YUICompressor',
    'YUI_JS_ARGUMENTS': '--nomunge --disable-optimizations',
    'YUI_BINARY': '/usr/bin/yui-compressor',
}

Is this a bug or have I misconfigured Pipeline?

The image appears to be the trigger. Pipeline fails on any CSS file that contains a url() to an image. This is a pretty massive bug, as virtually every major Javascript and CSS library I use contains files like this.

I'm using version 1.6.13, the most recent version. Is this a known issue?

[chrisspen]

I tried switching storage backends, but they all experience similar problems.

The most stable backend appears to be the pipeline.storage.PipelineStorage, but that ignores files listed in ModelAdmin's Media.js list. Is there any way to get these files included?

I"m facing the same issue while deploying my django app using heroku ,please can anyone help soon?
