I think the openpgp part is the same since 1.0.x. Hasn't really changed.

This should be doing the convertion to raw encoding. Then
it proceeds if only if conversion to base64 is needed.

This should be correct since decoding should fail (check that the output
pointer is NULL so there is no place to copy the output). That call is
there to get the size of the exported key only.

You're not really supposed to call this function directly! :)
But anyway did you notice failures in this function?
