Description

When RADOS Gateway cannot perform RGWStoreManager::get_storage() sucessfully (which could be caused by eg. problem with authentication to the Ceph cluster), this method returns NULL. However, the failure isn't properly handled in main() and leads to segfault due to NULL pointer derefernce.
