When SIV (http://rh-software.com/) does a ShellExecuteEx() with the URL
http://rh-software.com/ this fails and the following error reported.

err:winebrowser:get_url_from_dde Unable to retrieve URL from string L"""
err:winebrowser:wmain Usage: winebrowser URL

Doing the same with mailto:[e-mail] though works.  To reproduce this
download http://rh-software.com/downloads/siv.zip unpack the files, run
SIV.exe, press [About] and then press one of the hot links as shown in the
attachments.
