When lvm_list_pvs_free lvm2app library function was called on a system with no physical volumes, a segmentation fault occured because lvm2app code tried to free an internal structure that had already been freed before. This has been fixed and the segmentation fault does not occur anymore when calling lvm_list_pvs_free function.
