Properties truncated to 7 character strings?

[wengole]

It seems all properties are only coming through as strings of 7 characters. For example

{'_parent': <pyzfscore.zfs.ZDatasetProperties at 0x7fcdb5d38150>,
 '_value': '1428313',
 'name': 'creation',
 'source_name': 'tank@test-snap1',
 'sourcetype': <EnumValue: zprop_source_t.ZPROP_SRC_NONE [value=1]>}

{'_parent': <pyzfscore.zfs.ZDatasetProperties at 0x7fcdb5d38150>,
 '_value': 'tank@te',
 'name': 'name',
 'source_name': 'tank@test-snap1',
 'sourcetype': <EnumValue: zprop_source_t.ZPROP_SRC_NONE [value=1]>}
