Vista Windows Explorer Searching Bug?

Thanks to Chris123NT for this one:

So, I’ve run across what seems to be a very serious bug in Windows Vista and it still exists in Service Pack 1 RC1 (and I really don’t know if this is going to get fixed in SP1 either, although I would hope so).

Can anyone reproduce this? I would love to have some good customer feedback on this one.

1. Click on Start, and then click on Documents.
2. In the Search entry box, type “NOT Shortcut” (without the quotes).
3. Click on the “Save Search” button and save the search query as “Search Test”.

In 9 out of 10 tries, Windows Explorer will stop working and will restart itself after displaying a crash dialog. Seems to be an issue with how the search files are serialized. How the hell did this one get past quality assurance? It occurs in both RTM and SP1.

The thing that bothers me here is that Microsoft is closing this bug as NoRepro (Not Reproducable). With so many people on the internet saying it happens to them, why is MS taking such an arrogant stance?
