xfconf-query uses g_ascii_strtod which always uses LANG=C. The
functions which does the string conversion is used for both stored
strings as user input. If you consider this a but, you can report this
as such at http://bugzilla.xfce.org

I don't know the application in which this program is used and if
these are applicable solutions. But you could use a printf alternative
which doesn't use the local output or set LANG=C when executing this
program.
