Can you try 3.4.x, this is most likely fixed there.

I'm afraid I can't, I modifie that code and don't have
an exact backup... I learned the lesson for the next

So lets close this now, I think there was a bug like this already fixed on the mainline also.

mainly this:

So fixed so closing as such.

Also this is a most likely a dup of bug 11616.
