Bundles loading error : Decompression failure

Hello,

I have a lot of random error while loading bundles in my app. THe message is :
“Invalid unity web File : (Decompression failure)”
If I hit refresh button, sometimes it works, sometimes the loading failed a little bit later, sometimes it another file which failed …
It seems that once it is in the browser cache the error doesn’t appear anymore
I use Unity 3 f5 and I Find that my webplayer (on firefox) is f6.

I have a loop which load a collection of bundle like this :

...
for (int j = 0; j < m_PacketToLoad.Count; j++)
{
   m_curPacket.m_status = Packet.status.loading;
   m_WWW = new WWW(m_curPacket.m_fullPath);
   yield return m_WWW;
   if (m_WWW.error != null)
   {
      Debug.log(("Loading ERROR : " + m_WWW.error);
   }
...
}

The same project worked perfectly on Unity 2.6

Look very strange. Any Idea ?

Thanks

same here with 2.6…
