Project Generate ODT and ODS - HTTP ERROR 500 and more

Hi Guys,
I found error on project generate document ODT or ODS, first you must create a new document on Openoffice, this document must be cleaner. Second, all document must has 3 lines unformated write on somewhere:

[!-- BEGIN projectcontacts --][!-- END projectcontacts --]
[!-- BEGIN projectfiles --] [!-- END projectfiles --]
[!-- BEGIN projectrefs --] [!-- END projectrefs --]

Good Look !
