Auto minify creating wrong src in html

Hi,
I’ve just installed w3-total-cache to try it out and I found a few bugs with the minify feature.
First, as it is told in another thread, I’m getting a filename length error when I have the automatic filename test enabled. I’ve disabled it and set the filename length to 246 and it seems to create the minified files correctly.
But the href from the stylesheet and the src from the script are incorrect. I’m getting “${host}/blog/wp/-content/cache/minify/000000/…” instead of “${host}/blog/wp-content/cache/minify/000000/…”
If I correct the link in the browser url the files are correctly returned.
I’m using a remote memcached as storage and my wordpress installation has the particularity that I have moved the wp-content folder to the parent folder.
-> /blog/
—> /blog/wp/
—–> /blog/wp/wp-includes/
—–> /blog/wp/wp-admin/
—> /blog/wp-content/

Thanks
