STM32F0 SPI Slave wrong behaviour

I'm stuck in my project by this spi problem. What i do is simple, i send a data from a stm32f0 (master) to another one (slave) but here is the problem: while i see on the scope the good frame, the slave device doesn't. More precisely, it sees the data divided by 2. Plus i have to send the data twice to make the slave device understand something other  than 0x00..
In the case of the slave, i handle the communication by interrupt whereas the reference manual says that it is preferable to use DMA.

Do anybody found this problem someday?? I really need to work this out
