A little experimentation shows that removing the polyglossia package,  
or even just removing the [latin] option from polyglossia in your  
sample, resolves this issue.

So it seems to have something to do with how polyglossia patches the  
headers, trying to ensure they appear in the expected font even if the  
main text might be using a different language and font at the moment  
the page-break happens. Looks like an issue for François to  
investigate......
