Yes, that's what I was wondering. But alas, that's aparently not the
reason.

This is going to be a bit more complicated, sorry :(

Could you try to reproduce the problem, and do 'p/x ReadRecPtr'? That
should give you something like 0x5434343496. If you rewrite this as
first-four-bytes/last-four-bytes e.g. 54/34343496 you get the LSN. With
that, could you try
pg_xlogdump -p /path/to/data/directory -s 54/34343496 -n 100
and send the output?
