This happens because in `SEQ_time_update_sequence` function `SEQ_get_meta_by_seqbase` returns uninitialized value. This isn't nice, but it shouldn't happen in first place. Problem is, that `SEQ_edit_strip_split` does move strips into detached `ListBase`, so other functions can't see them anymore. Detached `ListBase` is used solely to preserve relationships during duplication. Move strips to original `ListBase` immediately after duplication and return `NULL` if `SEQ_get_meta_by_seqbase` can't find meta strip. Splitting itself can still rely on fact, that number of original and duplicated strips is same and they are placed next to each other in exactly same order at the end of original `ListBase`.
