Lightroom: Publish Services doesn't display folder name correctly (French/Mac)

Hi,

In LR, I have an intermittent problem where for Folders published to Hard Disk, the folder name sometimes is not visible, only the number of items in the folders. See the 2 attachments. I have to quit LR and restart the application to resolve the problem, until it happens again a few days later. My system is in french.

Is this a known bug?

Thanks,
