Thanks for your reply, some days after my post, somebody has open a bugs:
https://bugs.dojotoolkit.org/ticket/19100
unfortunately to date without resolution.
I think it’s a Chrome problem. The error a line 80 of dojo-release-1.13.0-src\dojox\mobile\iconUtils.js:
var rules = sheet.cssRules || [];
sheet.cssRules raise an exception “Cannot access rules”.
I tried a workaround but without succesful.
