Exception Type: DatabaseError at /deals/share/
Exception Value: ERREUR:  séquence d'octets invalide pour l'encodage « UTF8 » : 0xe9e9e9
HINT:  Cette erreur peut aussi survenir si la séquence d'octets ne correspond pas
au jeu de caractères attendu par le serveur, le jeu étant contrôlé par
« client_encoding ».

Basically it says that the encoding was not valid for UTF8 and contained   0xe9e9e9

This seems quite strange,

Any hints on where it could come from ?

U+00E9 is LATIN SMALL LETTER E WITH ACUTE.

This MAY be the source (not necessarily the cause) of the problem: 'title':u"éééààà",.

Cause may be something like your_title.encode('latin1').decode('utf8') (not in one step, of course).
