[Shotwell] [Ubuntu 11.10] Failed upgrade to 0.12.1

[Damien Lecan]

Hi,

I'm a user of Shotwell for a long time and I used to play well with
Shotwell 0.11.x on Ubuntu 11.10.

I'm using Yorba PPA, so today, upgrade to 0.12.1 was automatic.

But I can't open my Shotwell database anymore :(
See error log below :

L 3411 2012-04-01 21:55:06 [DBG] util.vala:162: next step: Tag.init
(23606/45825)
L 3411 2012-04-01 21:55:07 [CRT] AppWindow.vala:662: Une erreur fatale
est survenue lors de l'accès à la photothèque de Shotwell. Shotwell ne
peut pas continuer.

(DatabaseTable.update_text_by_id_2 TagTable.name) [19] - constraint failed

What to do ?

Thanks

Damien
