There might be some warning or error message before the file content. To 
see the message, try downloading a plain text file and look at it. On 
Linux, you can peek into the ZIP file with `less -L file.zip`, agree to 
view the binary file and look at the first few characters or lines, 
before the string "PK^C".

Alternatively, some recipe or local configuration may output something 
before the file. This may happen if you have PHP files with a closing 
"?>" marker at the end, and some text or white space after it. It is 
recommended to remove these closing markers from your local and cookbook 
files.

See PmWiki:Troubleshooting on how to track the source for the 
errors/warnings.
