On the fly conversion of flac files does not work in gtkpod

[Michael Stockenhuber]

Adding flac files to ipod, the following error message is displayed:
Conversion of ' ' failed: '/usr/share/gtkpod/scripts/convert-2mp3.sh ' returned exit status 4.
Should convert and add files to ipod.
remedy:
install flac using:

sudo apt-get install flac

Dependency of gtkpod from package flac should be added to package.
Works once package flac is installed

Ubuntu 14.04

output from:
