[Muscle] md5sum signatures

[Goger Klaus]

I've got a /little/ problem with signatures and the MuscleCard Applet  
0.9.8.
When i try to sign some md5 hashes this doesnt work with every hash. I  
can't locate the a pattern in the md5 what actually make it unusable.  
But the "signme" example isnt working for me on different cards (see  
below for more info about used software and hardware)

$ echo -n "signme" | md5sum
d65a65a5e0ce29e5f28ef3069d974761      // doesnt work for me
$ echo -n "1234" | md5sum
81dc9bdb52d04dc20036dbd8313ed055     // Works on every card for me
