Bug in error message (computing partial matches) for array[Array with ndim > 1]

[gdementen]

>>> arr = ndtest("a=a0;b=b0..b1;c=1..2")
>>> key = ndtest((1, 2))
>>> arr[key]

TypeError: unhashable type: 'Array'

For a 1D array key, it works as it should:

>>> arr = ndtest("a=a0..a1;b=1..2")
>>> key = ndtest(2)
>>> arr[key]
ValueError: a  a0  a1
    0   1 is not a valid subset for any axis:
 a [2]: 'a0' 'a1'
 b [2]: 1 2
Some of those labels are valid though:
 * axis 'b' contains 1 out of 2 labels (missing labels: 0)
