Double hit of 'Return' key breaks indentation

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Type example code:

if a is None:
    a = 1

2. When the cursor is after "a = 1" double hit "Return/Enter" key.

What is the expected output? What do you see instead?
Indentation should be preserved, but after the second hit the cursor returns to 
the beginning of the line.

What version of the product are you using? On what operating system?
2.5.3.0 on Windows 7 (x86)
