ReactiveUI.UnhandledErrorException: An object implementing IHandleObservableErrors (often a ReactiveCommand or ObservableAsPropertyHelper) has errored, thereby breaking its observable pipeline. To prevent this, ensure the pipeline does not error, or Subscribe to the ThrownExceptions property of the object in question to handle the erroneous case.

I am indeed, and that was the issue, I built a fresh build of 1.7.0 from handbrake because when you released your new version that's what they had defaulted in their git. a quick tag switch to 1.7.2 and all's right as rain. (at least with this issue.)
