Sending a file with spaces in the title causes network connection errors

[abbeycode]

Spaces cause bogus error messages, like:

Error Domain=NSURLErrorDomain Code=-1001 "The request timed out." UserInfo=0x6080000e5500 {NSUnderlyingError=0x60800024da70 "The request timed out.", NSErrorFailingURLStringKey=https://.s3.amazonaws.com/File%20With%20Spaces.zip, NSErrorFailingURLKey=https://.s3.amazonaws.com/File%20With%20Spaces.zip, NSLocalizedDescription=The request timed out.}

and

Error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost." UserInfo=0x6080000ecd80 {NSUnderlyingError=0x608000059620 "The network connection was lost.", NSErrorFailingURLStringKey=https://.s3.amazonaws.com/File%20With%20Spaces.zip, NSErrorFailingURLKey=https://.s3.amazonaws.com/File%20With%20Spaces.zip, _kCFStreamErrorDomainKey=4, _kCFStreamErrorCodeKey=-4, NSLocalizedDescription=The network connection was lost.}

Replacing spaces in the destinationPath with "+" allows it to go through correctly. The resulting file shows up in the S3 console, with spaces intact.
