I think, yes.
Tvb-s are marked as expired after calling a Lua dissector to prevent Lua from
using a freed tvbuff_t*.
We could mark the Tvb-s later, when wireshark frees the tvbuff_t* after the
whole frame is dissected to avoid the mentioned "expired tvb" errors.

Could you provide a simple example to reproduce the error?
