JsonEncode with proxies

Hi there,

While playing around with your excellent library i noticed a problem when using JsonEncode with a proxy (or with an object containing a proxy).

FATAL 56: uncaught error
PANIC 56: uncaught error (calling abort)
SIGABRT: abort
PC=0x7fff8772d0ae
signal arrived during cgo execution

goroutine 7 [syscall, locked to thread]:
runtime.cgocall_errno(0x40030f0, 0xc2080f1280, 0x0)
    /usr/local/go/src/runtime/cgocall.go:130 +0xf5 fp=0xc2080f1260 sp=0xc2080f1238
github.com/olebedev/go-duktape._Cfunc_duk_json_encode(0x5c04130, 0xffffffff, 0x0)
    github.com/olebedev/go-duktape/_obj/_cgo_gotypes.go:882 +0x44 fp=0xc2080f1280 sp=0xc2080f1260
github.com/olebedev/go-duktape.(*Context).JsonEncode(0xc2080320d0, 0xffffffffffffffff, 0x0, 0x0)

The problem can be reproduced with the following unit test

func (s *CandySuite) TestPushProxyJson(c *C) {
    s.ctx.PushGlobalObject()
    s.ctx.PushObject()
    // note: it works when using a struct instead of a proxy!
    // s.ctx.PushStruct(&MyStruct{Int: 142})
    s.ctx.PushProxy(&MyStruct{Int: 142})
    s.ctx.PutPropString(-2, "obj")
    s.ctx.PutPropString(-2, "foo")
    s.ctx.Pop()

    // note: also fails with script `foo`   
    err := s.ctx.PevalString(`foo.obj`)

    c.Assert(err, IsNil)
    s.ctx.JsonEncode(-1) // *BOOOM*!
}

Any ideas why it fails and/or how to fix this?
thanx.
