It might be a Spyder bug though since I can't reproduce it in a stand alone ipython console.

This for example works (the first time):
``` python
import numpy as np
import pandas as pd
import xarray as xr

da = xr.DataArray(
    np.array([1, 2, 3, 1, 2, np.nan]),
    dims=""time"",
    coords=dict(
        time=(""time"", pd.date_range(""01-01-2001"", freq=""M"", periods=6)),
        labels=(""time"", np.array([""a"", ""b"", ""c"", ""c"", ""b"", ""a""])),
    ),
)
da.groupby(""labels"").count()

da = xr.DataArray(
    np.array([1, 2, 3, 1, 2, np.nan]),
    dims=""time"",
    coords=dict(
        time=(""time"", pd.date_range(""01-01-2001"", freq=""M"", periods=6)),
        labels=(""time"", np.array([""a"", ""b"", ""c"", ""c"", ""b"", ""a""])),
    ),
)
da.groupby(""labels"").count()

Is it just me that this example crashes the second time I run it?
``` python
import numpy as np
import pandas as pd
