The crash is fixed, this bug should be closed and a new one opened for saving not working.
I was going to, but I just tested it in 1.8-rc2 and saving now works when the Windows version is set to Vista or 7. I don't know what fixed it, but based on comment 17 it must have been fairly recent.
A bisect would be useful if you can.
