Problem generating kmail documentation in KF5 trunk

[Freek de Kruijf]

I finished translation of nl/docmessages/kmail/kmail2_faq.po and tried to 
generate the documentation of kmail using:

scripts/update_xml nl kmail

I got the following output:

I could not find what's wrong.
Generating the documentation for KF5 branch works OK.
