Thanks for mentioning that, it can matter as the code that stitches
split hunks back together can't cope with edited hunks properly (though
the code that checks the hunk immediately after it's been edited doesn't
bother to try and stitch things back together).

I'm not quite sure what that error message is telling us, I need to
spend some time understanding the code in apply.c that creates this
error message.
I assume that the header is coming from the next hunk which was created
when you split the original hunk. If you could post the original hunk
before it was split and the hunk starting at line 25 after it was split
that might help.
As Martin said if you could share the files or come up with a
reproducible example that would really help in figuring out what is
going wrong.
Thanks for reporting this
