cygwin's subversion-1.10 broke zsh's svn-completion

[Chris via cygwin]

Hi,

after upgrading to subversion-1.10 in cygwin, the command completion in zsh for svn no longer works.
I don't get the same problem on Linux where the completion still works with subversion 1.10, so to me it looks like something cygwin-specific, but I can't be sure. I don't know if I should direct this issue here, to zsh or subversion, but since it does works in Linux, I suspect this is the right place.

When pressing tab after writing "svn ", I'm getting:
_svn:33: bad set of key/value pairs for associative array

Anyone has any ideas?

/Chris
