class option 'sans' is ignored when using polyglossia

[Stefan Fischer]

\documentclass[11pt,a4paper,sans]{moderncv}
...
\usepackage{polyglossia}
\setdefaultlanguage{german}
...

XeLaTeX + moderncv
------------------
- Loading polyglossia is fine.
- But using polyglossia's \setdefaultlanguage{...} command results in a document with a *serif* font.

[Xavier Danaux (xdanaux)]

Just so I understand:
 - without polyglossia, you get your resume with a sans font, but
 - with polyglossia and \setdefaultlanguage{german}, you get a serif font despite the sans class option.

Is that correct? If it is the case, the problem seem rather to be with polyglossia imho. Also, what style variant are you using?

[Stefan Fischer (sfischer13)]

I use \moderncvtheme[red]{banking}.

This doesn't cause a problem. That is, I get a sans serif font.
\usepackage{polyglossia}

But when I additionally call 'setdefaultlanguage', I get a serif font.
\usepackage{polyglossia}
\setdefaultlanguage{german}
