Sjourney on "[Plugin: WooCommerce - excelling eCommerce] Invalid virtual download (key ID bug?)"

Running WC 2.0.8
Have 1 simple product w/ 3 virtual downloadable PDFs bundled
the three download URLs are as follows:

http://blah.com/?download_file=3284&order=order_51758569a9f61&email=blah.blah@gmail.com&key=6ac68fb90702a72a7ef9c508025583a4

http://blah.com/?download_file=3284&order=order_51758569a9f61&email=blah.blah@gmail.com&key=bad6a275f58467d31629a642f876b063

http://blah.com/?download_file=3284&order=order_51758569a9f61&email=blah.blah@gmail.com&key=43525530dc7761b931d92ff%203c0c1b748

I noticed a discrepancy between the keys of the 3 downloads:

1. 6ac68fb90702a72a7ef9c508025583a4
2. bad6a275f58467d31629a642f876b063
3. 43525530dc7761b931d92ff%203c0c1b748

Notice the third one has more chars than the previous 2, and is coincedentally returning an Invalid download page. It's showing a 500 in the apache access.log file when I try to download the 3rd file.

Any ideas?
