The following code panics - it should return an error, at the least.
4a8268927758+ weekly/weekly.2011-12-22

package main

import (
    "bytes"
    "fmt"
    "gob"
)

func main() {
    var buf bytes.Buffer
    enc := gob.NewEncoder(&buf)
    enc.Encode([]byte("hello\n"))
    dec := gob.NewDecoder(&buf)
    var b []uint32
    err := dec.Decode(&b)
    if err != nil {
        fmt.Println("error: ", err)
        return
    }
    fmt.Printf("%v\n", b)
}

i get this result:

panic: interface conversion: gob.gobType is *gob.CommonType, not *gob.sliceType
[recovered]
    panic: interface conversion: interface is *runtime.TypeAssertionError, not gob.gobError
