I see this has been fixed now, but just to make sure. dpkg in Jessie
does not perform the dependency checks anymore on trigger processing,
so that's why you are seeing this problem now. Switching to noawait
helped mainly to avoid trigger cycles or to reduce the dependency
graph complexity, so this would be unrelated.

Thanks,
