ok, the problem seems to be if there is any null because this works:
```
>>> array2 = pa.array(['String longer than 12 characters', 'Short'],
type=pa.string_view())
>>> new_array = pa.StringViewArray.from_buffers(pa.string_view(),
len(array2), [array2.buffers()[1], array2.buffers()[2]])
>>> new_array
<pyarrow.lib.StringViewArray object at 0x73fc88321f60>
[
null,
null
]
>>> new_array.buffers()
[<pyarrow.Buffer address=0x3bac00303c0 size=32 is_cpu=True is_mutable=True>,
<pyarrow.Buffer address=0x3bac0030400 size=32 is_cpu=True is_mutable=True>]
```
even the original works if I cheat and tell from_buffers that the size is
one less than expected (avoid the null at the end):
```
>>> array1 = pa.array(['String longer than 12 characters', 'Short', None],
type=pa.string_view())
>>> pa.StringViewArray.from_buffers(pa.string_view(), len(array1)-1,
[array1.buffers()[1], array1.buffers()[2]])
<pyarrow.lib.StringViewArray object at 0x73fc88321f60>
[
null,
null
]
```
This seems like a bug :)
