Description of problem:
Amarok isn't currently able to transfer files with unicode characters in their
filenames. For example, when transferring files with accentuated characters (á,
é, í, ó, ú, à, è, ì, ò, ù, ä, ë, ï, ö, ü, etc) and special characters (ñ, €, ø,
ß, etc) to an MTP device (iriver Clix in my case), Amarok will spit an error
message stating tha the file couldn't be transferred. Without further
explanation. I have to resort to transfer these files manually with the
mtp-sendfile or mtp-connect --sendfile commands from the CLI to transfer these
files, however this avoids the internal database and album appendage (not to
mention also skips any metadata on the files), this has been particularly
difficult with .ogg files (which my Clix supports just fine) 

Version-Release number of selected component (if applicable):
amarok-1.4.5-4.fc6
libmtp-0.1.5-1.fc6

How reproducible:
Always

Steps to Reproduce:
1. Start Amarok and attach an MTP device
2. Browse to some files with unicode characters in their filenames
3. Try to synchronize/transfer those files to the MTP device
  
Actual results:
Amarok will spit some generic errors about the files not being transferred

Expected results:
The files to transfer, as they're easily transferred using the mtp command line
tools
