Hello again,
Please ignore this thread. It turns out that I was using a Biostrings
version where Views was in the process of being modified. I just
re-installed Biostrings and Views works correctly using R 2.14.0devel.
Sorry for the spam >.<

### What I want to do works well now in R 2.14.0devel :D
### The examples for XStringViews have warnings but those are intended!

Warning messages:
1: Using XStringViews(..., subjectClass="RNAString") on an XStringViews
object is deprecated. Please use 'xsbasetype(x) <- "RNA"' instead.
2: Using XStringViews() on a AAString object is deprecated.
Please use 'as(x, "Views")' instead.
3: Using XStringViews() on a character vector is deprecated.
Please use instead something like:
as(BStringSet(x)), "Views")
if you really want views, otherwise just:
BStringSet(x)
