Auto Minify CSS returns “400 Bad Request”

I have a WP installation where W3TC’s Auto Minify CSS feature is broken:

• Fresh WP install, no plugins
• W3TC v 0.9.5.4
• All features disabled, except Minify CSS Auto, no URL rewriting

All URLs to the minified CSS file(s) return a 400 “Bad Request”.
How to fix this and let me know if more details on the server setup is needed!

Thanks,

Martin
