Each time I boot LinuxMint 13 Mate, I get this message : The language fr_CA doesn't exist. Will use the system by default (in french: la langue fr-CA n'existe pas. Utilisatiion de système par défaut). I have to click OK each time if I want the system to complete the boot, which is pretty annoying. I have chosen the French language at installation and made all the available updates. The error message doesn't provide a single hint or clue about what service or software may cause that error at start up.
First time it ever happens to me since Mint 6.
Any idea ?
