Dates repeated when applying culture

[Just]

In my grid the dates shown in the date column are repeated with the date values for the first row. The dates show fine if I remove the globalization

kendo.culture("en-GB");

Field is defined like this

, { field: "StartDate", title: "Date", width: 80, format: "{0:d}" }

The date values received over the wire are fine. But when I tap into the "change" event of the datasource or the "databound" event of the grid I see that the data in the model is already modified.

I am not sure what's happening here. Anybody has any ideas what could be wrong? I am using Kendo v2012.2.710.

Thanks.
