Many thanks for your reply, Max,

I’m afraid I cannot make your proposed fix work.

For the sake of consistency (with buff-imp-xml.lua), I think the patch
should read (also attached to the message to avoid wrong line breaking):

But I’m afraid I cannot make it work on my computer (Linux64).

On another Win64 computer, both patches worked perfectly fine.

Both machines run LMTX current latest. So I have an issue on my
installation that I have to fix first.

Many thanks for your help,

Pablo
