[Plugin: Better WordPress Minify] Conflicts with White Label CMS custom login page CSS

When enabling BWPM, my custom css for the login page, provided with the White Label CMS plugin, breaks. If I disable automatically minifying of css files it works fine.

Any idea how I can get BWPM to not minify the custom css created by White Label CMS?
