Well, the error I had was this one:
"FATAL: Extra content at the end of the document"
https://gitlab.com/xen-project/hardware/xen-staging/-/pipelines/1848598740/test_report

And indeed, when I managed to dl the junit.xml, there were the end of
the document duplicated many times.

I managed to find in matrix where they were talk about this duplication
of data, well, with `nc` dl for ever, with lots of duplicated data:

I have no idea if it is the same issue, but I had extra content in the
junit file with nearly all my jobs.
