I have this same problem. It happens when I record a voice message and when I use the "Use this recording" that same message comes up and if I answer OK, Ringdroid shuts off.
i created an app that fixes this problem. it's on Google Play (search for "ringdroid qcp fix"). i would appreciate downloads from the market, but you can also get it from bode Pauer . . . look for "bP record".
