Jonathan Potter just sent his patch for TortoiseSVN.
I've applied the patch in r17777, merged it back to the stable branch and started the build.
You can download a fresh nightly build from the stable branch from here:
http://nightlybuilds.tortoisesvn.net/1.6.x/win32/
in 2-3 hours.
Note: the nightly builds from the stable branch are what will become the next release. No new features are added there to prevent introducing new bugs. Only bugfixes are applied there. So there's little risk in using that nightly build (despite of its name "nightly build").
