Wiki history lost?

[Philippe Cloutier]

Hi,
as noted on #amarok, it seems there was a problem with wiki history. 
Page history shows the last version plus those posterior to about 
February 9. Recent changes shows older changes, but it's not always 
possible to see the diff (for example 
http://amarok.kde.org/amarokwiki/index.php?title=Fr:Requirements&curid=1176&diff=11717&oldid=10686 
)
Is someone aware of what happened?
