[Inkscape-translator] Can't edit the wiki - content gets erased when saving

Hi, I trying to create this wiki page: http://wiki.inkscape.org/wiki/index.php/ReleaseNotes047-es with the copied content from http://wiki.inkscape.org/wiki/index.php/ReleaseNotes047 but when I save the content keeps getting erased and appears completely blank. This only happens when I copy the complete text of the original release notes, not when I copy small parts of it. I seems to break at a certain number of characters. Is this a known behaviour? (I'm using Firefox 3.0.13 on Suse Linux)

If this persists, what can I do? Should I breakthe Release notes in two pages?

Thanks,
