I don't have a crash, nor I don't have valgrind, Evan can you check if after:

@@ -1183,7 +1183,7 @@ fragment_add_work(fragment_head *fd_head, tvbuff_t *tvb,
const int offset,
        }

        if (old_tvb_data)
-               tvb_free(old_tvb_data);
+               tvb_add_to_chain(tvb, old_tvb_data);

use after free errors goes away?
