Sorry, I misread your original post. I understand your question now.
There was a recent change (March 2 and 3) to the dialer, where Google's was dropped in favor of a open source version. This was need in order to introduce multi-SIM support. The new dialer looks like it's still missing quite a few things, possibly including bits that are used by other dialer apps.
If you want to get the old dialer back, you could try getting hold of the 0301 build (or earlier) and pulling the bits you need from there. Hopefully there haven't been any breaking RIL changes that would stop the old version from working.
