MD5-Hash of a SHA-1-Hash unsecure?

Hey guys,I've written a program which can store files encrypted ( http://h4des.org/index.php?inhalt=kastalia ). The user enters a password when he wants to encrypt a file. The programm makes a SHA-1-Hash of this password and transfers it from the browser to the server. When the encryption starts, the program makes a MD5-Hash of this SHA-1-Hash for the IV of the blowfish algorithm.
Here is my question: Is it less secure when I make a MD5-Hash of a SHA-1-Hash? Regards, -- [] Andre Pawlowski visit http://h4des.org
