Multiple import same namespace for go included files

When I include two files with same namespace for go language:

include "common/Exceptions.thrift"
include "common/Typedefs.thrift"

And generate it for golang in result in import I have import of this namespace twice:

import(
   "bytes"
   "context"
   "reflect"
   "fmt"
   "github.com/apache/thrift/lib/go/thrift"
   "my_namespace"
   "my_namespace"
)

And when I try to use I have an error because of this:
"'my_namespace' redeclared as imported package name"
