Fixed
Issue : on android and in gmail chat, some contacts' avatars aren't showed but you can see it on their profil ...
Reason : there is a bug on adresses containing points ".".
Solution : you must rename all these contacts by removing the point (toto.tata@gmail.com and tototata@gmail.com are the same adress)
However that fix won't work for yourself because gmail gives priority to toto.tata instead of tototata. Waiting for a google real fix !
