  Ah ah, now I can reproduce it:

paphio:~/XML -> xmllint --noout fotoarchief.xml
fotoarchief.xml:537: parser error : Comment not terminated
etc...
paphio:~/XML -> cp fotoarchief.xml fotoarchief2.xml
paphio:~/XML -> dos2unix fotoarchief2.xml
dos2unix: converting file fotoarchief2.xml to UNIX format ...
paphio:~/XML -> xmllint --noout fotoarchief2.xml
paphio:~/XML ->

 Clearly there is a low level libxml2 parser bug, congratulation !
 I will try to look at it during the week-end, this kind of errors 
have become quite uncommon, interesting ! Tanks a lot for reporting it !
