Hello :) i'm a happy user of the wonderfull Odoo V9 community edition :)

I'm using it on a Debian Jessie serveur with Nginx where Odoo was instaled thru the nighly builds Odoo package.

Everything is working fine except when i want to print.

When i would print a quote, an invoice, on someone else i always have this error:

[code]

TypeError: this.contentDocument is null

jQuery.event.add/elemData.handle@https://my-domain.tld/web/content/6713-1faa9da/web.assets_common.js:713:151

[/code]

in another way when i would send a document by mail i have this error:

[code]

Wkhtmltopdf a échoué (code d'erreur : -6). Message : The switch --header-spacing, is not support using unpatched qt, and will be ignored.The switch --header-html, is not support using unpatched qt, and will be ignored.The switch --footer-html, is not support using unpatched qt, and will be ignored.QXcbConnection: Could not connect to display

[/code]

is someone have an idea to where i should look to solve there issues ?

thank you very much by advance for your help :)
