[news.eclipse.platform.rcp] Problem building update site

[Patrick Godeau <godeau_nosp@xxxxxxxxx>]

Hello,

I'm migrating my RCP app from Eclipse 3.2 to 3.4.

All went fine (with some effort) but now I have a problem when I build 
update site (site.xml).

I get this error message: "Problems during export".

And clicking on Details:

Problems during export
