Windows line endings, then? The keys aren't empty, but contain "\r" at the end. When printed, the character moves the cursor to the beginning of the line, and the value then overwrites the key. Convert your files to the *nix format using dos2unix or fromdos, or apply 
s/\r//

to your input lines.

    Your quite right - the data wasn't in unix format and the function suggested solves the issue. Many thanks indeed!
