34 playlists have "mustDescent", but not "isDirectory" - you don't want the user to browse inside the playlist (unless he really wants)

197 Python code has to check the returned pointer against 0. This works,
198 as all functions returning instances in smartpointers AND having a
199 RESULT have to BOTH return non-zero AND set the pointer to zero.
201 Python code thus can't check for the reason, but the reason isn't
202 user-servicable anyway. If you want to return a real reason which
203 goes beyong "it just doesn't work", use extra variables for this,
206 Hide the result only if there is another way to check for failure! */
