I can reproduce the bug, and I also get the same (faulty) result with vanilla vte-0.48 compiled by me (that is, not the Ubuntu package, contrary to comment 7).
Jeremy, could you please test if bringing back 91_keep_fds.patch solves the issue? The error message sounds suspiciously related to what this patch was doing.
vte2.91 (0.51.90-1ubuntu1) bionic; urgency=medium

* Dropped change, apparently hasn't been needed for years:
- Add 91_keep_fds.patch:
+ Keep file descriptors open on vte_fork_pty()
