As a corollary, make sure you can actually use the functions from  
libmtp.  If the command-line functions won't connect to your device,  
Amarok won't be able to.  Usually this is a problem with udev  
permissions -- make sure you get the rules from libmtp and pop it into  
/etc/udev.d or wherever is appropriate.
