Current behavior

When compiling a Ionic2 application for AOT, the ngc compiler gives me this error.

ngc: Error: Error at C:/dev/ecdt-mobile/.tmp/app/app.module.ngfactory.ts:177:20: Generic type 'BaseService<T>' requires 1 type argument(s).

Expected behavior

It should compile. I have created an angular2 repro (without ionic) and it compiles fine. HOWEVER the generated code is underline in my IDE and I believe this is not right:

 __BaseService_76:import46.BaseService;

it should be something like:
__BaseService_76:import46.BaseService<any>;

Minimal reproduction of the problem with instructions

The repro project is here: https://github.com/graphicsxp/angular2
