 Currently, the following code fails:

 {{{
 sage: R = ZpCA(3,5)
 sage: S.<T> = R[]
 sage: W.<a> = R.extension(T^2-3)
 sage: W(W.fraction_field().zero())
 TypeError: Cannot convert
 sage.rings.padics.padic_ZZ_pX_CR_element.pAdicZZpXCRElement to
 sage.rings.padics.padic_ZZ_pX_CA_element.pAdicZZpXCAElement
 }}}

 The attached patch fixes this.
