The list is internal to GIRepository and should not be freed, nor should its string elements.
To check this, simply call (gir:repository-get-search-path) two times. The second one will fail because the pointer was freed.
The issue is that g-slist-to-list always calls (g-slist-free pointer) at the end. So a quick solution would be to add a param to g-slist-to-list that determines if the original list should be freed or not.
