Denis,

your build is not up to date. You'll need r44284 or later. With the  
current RC (which includes the fix) it works for me without problems:

 > french.dates <- c("7-déc-07",  "11-déc-07", "14-déc-07", "18-déc-07",
+ "21-déc-07", "24-déc-07", "26-déc-07", "28-déc-07", "31-déc-07", "2-
+ jan-08",  "4-jan-08",  "7-jan-08", "9-jan-08", "11-jan-08", "14-
+ jan-08", "16-jan-08", "18-jan-08", "21-jan-08", "23-jan-08", "25-
+ jan-08", "28-jan-08")
