step_into running 'til end

Hello,
recently I had a problem after installing xdebug-2.0beta5 on PHP 5.0.5.
The installation was fine, but when remote debugging, after the conection is 
stablished, and received the init packet, sending a command step_into 
(over/out, etc), makes the script run until end. 

On debugclient:

(cmd) step_into -i 1
<response command="step_into" transaction_id="1" status="stopped" 
reason="ok"></response>

Is there anything I might be missing?

Thanks,
+Thiago Silva
