It's rare but every now and then testing has an unsatisfiable dependency. It's usually resolved within a day or so. But I keep a lower distro around basically to insure I have a fallback, so I'm not blocked now. The next update should likely get me back to testing.
The conventional way to resolve temporarily unsatisfiable dependencies in Testing is to include Unstable at a lower priority, since that's where packages migrate to Testing from. Stable is a distinctly different distribution, and you're far more likely to see e.g. library ABIs from there incompatible with Testing.
