Did you notice the warning when you created the index:

Warning: The optimizer cannot use the index because the select list of
the view contains a non-aggregate expression.

So the index is not of much use. I guess you have hit a restriction
in SQL Server, which does not report as such in a nice way. When I
run your code in SQL 2005, I get:

Msg 1942, Level 16, State 1, Line 1
Cannot create index on view 'tempdb.dbo.aView'. It contains text, ntext,
image or xml columns.

Which is a more resolute message.
