compiling kdenlive 0.9 fails on nl-handbook

When I try to compile kdenlive 0.9 from source (for packaging purposes btw) I get an error while building the handbooks:

[code]
[ 1%] Built target pt_BR-handbook
[ 1%] Generating index.cache.bz2
index.docbook:21: parser error : Entity 'Ronald.Stroethoff' not defined
&Ronald.Stroethoff;
^
index.docbook:644: parser error : Entity 'vertaling.ronald' not defined
&meld.fouten;&vertaling.ronald;
^

make[2]: *** [doc/nl/index.cache.bz2] Error 1
make[1]: *** [doc/nl/CMakeFiles/nl-handbook.dir/all] Error 2
make: *** [all] Error 2
[/code]

Anyone else who has seen this error and knows how to fix?
