When will Plastic X have issue tracker support?

[RStroup]

When installing the latest version of Plastic over top of an installation already setup for Polarion Issue Tracking, I get an error when switching to the Pending Changes or Branch Explorer  views:

If I install the latest version to a fresh PC that didn't already have Plastic installed, I don't get the error, but I've also noticed that there isn't a way to configure an outside issue tracker.  Do you have a planned date to release a version that supports issue tracking integration?
