Not possible to disable caching

[keab]

libspotify has the possibility to disable caching by setting the cache path to empty string "".
However when I set cache_path = "" in spop, it instead created a cache folder named /""
Instead setting cache_path= (empty) , spop fails with "Can't create the cache path"
It would be good to be able to disable caching.
