[Shotwell] Directory monitor?

[Lorenzo Milesi]

Hi.
I have disabled photo directory watch in preferences, but when I fire up shotwell I find this in the log:

L 2598 2011-10-13 23:29:21 [WRN] DirectoryMonitor.vala:906: Skipping hidden file/directory /home/maxxer/Photos/2006/11/06/._IMG_1578.JPG.2dm6Gv

why is it monitoring, if it is supposed not to?

thanks
