See the post on the forum title Solution for 1680x1050 or read below. Basically the crash is caused by trying to run the game at 1680x1050.
After looking on the web for a while I found a solution to the Walhalla Exception error received when people try to run the program in 1680x1050.
The solution is ridiculous but I have tested it and it works. Simply run the game in 1680x1049.
The instructions below are copied from another forum
http://213.198.65.214/forum_DS/showthread.php?t=5305. All credit goes to the original poster. He/she explains it well. It is not hard and did not take me longer than a couple of minutes to set up.

1. You are using an Nvidia video card, and
2. You are willing to lose one 'line' of video on your LCD screen so you play at 1680x1049 as opposed to 1680x1050. Believe me, you won't notice the difference!
Here's the short of it:
You are going very easily make a custom resolution for your computer, and it will show up in the DarkStar One Display options window.
for ATI users: test this on your side, if in fact you can create your own custom resolution using the ATI control panel...
A#1 - Make sure you have the latest drivers!!
1. Go into the Nvidia Control Panel
2. Under Select a Task, look under the 'Display' list on the left.
3. Pick 'Manage Custom Resolutions'.
4. This window will allow you to bind new resolutions to your monitor.
5. Click 'Create'. A dialog box will appear.
6. Hit the 'Advanced' button so the whole dialog box is open.
7. At the top is a section called, 'Custom Display mode values'. Where it says 'Vertical desktop lines', Change the value from 1050 to a 1049.
8. At the bottom is a section called, 'Front-End Parameters'. Under scaling type, select 'CENTERED' and under 'active vertical lines' change the value from 1050 to 1049.
9. Hit the 'Test' button on the right, and Say 'yes' to accepting it.
10. Understand that this is NOT not going to change your current desktop resolution after accepting the results of the test. This just adds the new resolution you created to the list in the previous window.
11. You are done for now! Go into DarkStar One!
12. Under the Graphics menu, you will now see the new display setting.
13. Select your new 1680x1049 in the list and okay it. A message does NOT come up when you do this.
14. Exit the game anyway, and then get back into the game.
15. Tada!! perfect!
Edit: For ATI cards you can use PowerStrip to made a custom resolution.

My experience differed slightly from the directs above. After step 7 I skipped to step 11 as i had no 'Front End Parameters' to adjust. I think these instructions were written for older drivers. But as I said it works for me.
If anyone has any problems getting this to work post here to let me know. I am not an expert but maybe I can help.
