Hello.
Your issue seems to refer to the "Medical" project, not directly supported by
OpenERP so far. Luis Falcon knows better than us how far the porting of his
code to v6.0 has gone.
However, we are keen to help you debug this issue.

Please, do NOT use Windows when you want to write any decent code at all...

I just opened the file and found (copy-paste of 'less' terminal):
==> append : to filename to view the HTML source
<U+FEFF><?xml version="1.0" encoding="UTF-8"?>
="15.0" y1="42.0" width="539" height="758"/>
[[repeatIn(objects,'patient')]] LABO ...

See? Some editor is screwing your files.

Please allow me now to set this bug as invalid.

Sorry for the noise and many thanks for the feedbacks and tips. I was also just discover what is the culprit by switching back to the old day vi tool (vi -b). Gedit didn't report this to me (maybe I don't know the option to show all the hiden chars).
