Comment 1 for bug 1284641

No, it's not a duplicate. There's no proxy here, my bug affects the simplest deployment of subversion as long as 12.04 is used on the client and 14.04 on the server and spaces are used in file names in the repository

 It is a bug on the server, so in the newest version of subversion (1.8.8 released a few days ago)

And the symptoms are different. The double-encoding of space into %2520 is also found in the bug that I'm going to raise against 13.10, but not in this bug.
