Comment 5 for bug 1678022

Oh, I see the comment now about the double-encoded brackets. I tested using the same problem sub-directory, and I reproduced your issue if I use the decoded versions in the manifest. But if you use the encoded versions in your manifest, with:
"/OpenOffice.org%203.3%20%2528en-GB%2529%20Installation%20Files/"
then the GET on the large object will be successful. Does that solution work for you? I am actually not sure if swift claims to handle the double-encoding example. I will have to research that to see if this is a bug. But I am interested in solving your problem.
