With the console in QuickEdit Mode.
Print something to the console from blender.
1. Put your command prompt into quick edit mode.
Open a windows vista command prompt.
Right click on the border at the top.

On the Options tab in the Edit Options region check the QuickEdit Mode box.

Open Blender.
Go to the blender console window where python output is printed out.
Select an area by clicking and dragging the mouse.
Go back to the main Blender window.

Blender will crash.
Printing any string will cause the crash too.
Cheers, hope this is an ok one to fix, some (probably not important) details about my system follow.

Description
Event Timeline
What you see is probably some kind of timeout on which Vista reacts. Whenever you have a selection in the command prompt, it'll block the program that is running when it tries to output anything to the console. Execution continues when you remove the selection.
So I guess your Vista is seeing that blender is 'hanging' (due to the selection blocking), and probably tells you it should be closed or something.
I'm on Windows 7, but AFAIK this behaviour is also there in Windows XP when 'editing' the console.
So, please verify to see there's no actual crash, just blender stopping from responding. And report back soon. If no reports in a few days, I'll close this as a WONTFIX (Rejected), since IMO this is expected behaviour.
Reporter had trouble commenting, so in private email exchange it became clear that this is expected behaviour, although it's probably something one would not readily think of.
Toby suggested that there'd be a visual mark somewhere that blender is frozen, but the problem with that is... that blender is frozen. So for those who copy-paste from the windows console, in case of freezes, make sure you don't have any selection (any, meaning also the one cursor breadth selection in black somewhere).
Closing.
