By upgrading werkzeug,I resoled this problem.

For convenientI ,I made GreenOdoo9.0,it works very well.

I am having the same issue.

On stackoverflow i found a similar issue which was resolved by up[grading werkzeug. (hopefully this helps for you too)

Unfortunately this didnt work for me and i am still stuck.

Noticed that it is for all images that have a "data-default-src"

<img class="oe_topbar_avatar" data-default-src="http://odoo.sapelli.pe/web/static/src/img/user_menu_avatar.png" src="http://odoo.sapelli.pe/web/image?model=res.users&amp;field=image_small&amp;id=1">

where actually the data-default-source is working, while the "src" isnt

below the same error but with the 9.0 install
