Wheezy preseed installation installing too many packages

[John Dilley <john@johndilley.me.uk>]

I'm installing Debian Wheezy as a paravirtualised guest onto
XenServer, with a preseed file (below) - despite only asking for
standard system utilities in tasksel, I seem to be getting a full
desktop environment installed.

The preseed file was based on the one I use for Squeeze, which works
fine - is there anything I'm obviously doing wrong?

When I run the installer manually and deselect the desktop task in
tasksel (which is selected by default), then it installs only the
essentials. Do I need to add something in the preseed file to tell
tasksel to deselect the desktop task?

Any help appreciated, thanks.
