@benoit: If you click the link where I said it was fixed (the one in the link above), you should also see this line on the issue:
Since I assume you don't really have that version that doesn't even have a new version and build number yet, but only exists right here in my test environment, I'm not really suprised
ok but it is also marked "fixed" ;-) i don't know wat are the rules to see a case is fixed or not.
