Failing Tests in Trunk and Contributing a Patch

Failing Tests in Trunk and Contributing a Patch

I'm working on patching the slider control so that the range can be made draggable. I assumed I should just check out trunk and work off of that, but a lot of the unit tests are broken. Should I be working off of the latest stable release instead?

Also, once I have my patch, what's the preferred way to contribute it? Create a ticket and attach it to that?

Thanks!
