In fact I cannot :-) So please ignore this patch.
I wrote this while rebasing my code on top of your mttcg branch,
and then it was needed. However, patch 01/38 (which I wrote after
writing this patch) was the right fix, and I forgot to check whether
this patch was still necessary--turns out it wasn't.

Will do.
