Copy doesn't like directories with uppercase letters

[nheape]

When I use copy to copy files to a destination folder that includes uppercase letters, it fails.

When I use copy to copy files to a destination folder that has no uppercase letters, it works.

Example:

nick@raspberrypi:~ $ ~/bin/Dropbox-Uploader/dropbox_uploader.sh copy Apps/Fast\ Scanner\ App/jpegs Text/Notes/Scans/FastScanner
 > Copying "/Apps/Fast Scanner App/jpegs" to "/Text/Notes/Scans/FastScanner" ... FAILED
Some error occured. rerun the script with "-d" option and check the output and logfile: /tmp/du_resp_29993.
nick@raspberrypi:~ $ ~/bin/Dropbox-Uploader/dropbox_uploader.sh copy Apps/Fast\ Scanner\ App/jpegs Text/Notes/Scans/fastscanner
 > Copying "/Apps/Fast Scanner App/jpegs" to "/Text/Notes/Scans/fastscanner" ... DONE
