    window-slot: Clear pending_selection after freeing it
    
    This might not be the case when handling archive files, in fact we were
    freeing the list and assigning it to a new value for non-archive files,
    but in case of archives the list was just freed and the invalid pointer
    kept around, potentially causing a later crash.
