de jessie à jessie >> maj du sources.list

hello,
j'ai du raté un wagon car je viens de m'apercevoir que je suis en sid

uname -a ; cat /etc/debian_version ; cat /etc/issue

Linux debdesk 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt9-3 (2015-04-23) x86_64 GNU/Linux
stretch/sid
Debian GNU/Linux stretch/sid \n \l
 

Pourtant la version de thunar (je suis sur xfce) est celle de jessie...

Mon sources.liste avant de le changer:

# deb cdrom:[Debian GNU/Linux jessie-DI-b2 _Jessie_ - Official Snapshot amd64 xfce-CD Binary-1 20141003-18:31]/ jessie main
 
#deb cdrom:[Debian GNU/Linux jessie-DI-b2 _Jessie_ - Official Snapshot amd64 xfce-CD Binary-1 20141003-18:31]/ jessie main

#deb http://ift.tt/1ja912c stable-backports main contrib non-free
#Debian-jessie-backports
deb http://ift.tt/z3CdSe jessie-backports main contrib non-free

J'ai du passer en sid avant d'avoir eu le temps de mettre à jour mon sources.liste... Je me trompe?
