BadStatusLine exception on 'attach' command

What steps will reproduce the problem?
1. Start a script with the embedded debugger
2. run rpdb2
3. specify password
4. enter "attach" command

What is the expected output? What do you see instead?
I have exected to get th table of scripts to debug without a message about 
exception.
But i see a message about exception.

Password is set to: "test"

> attach
Connecting to 'localhost'...
