When running under valgrind, it claims that there's used uninitialized
memory, which is set as GObject property in the code. It's for
GtkLabel::xalign. The problem was that the value in the code is
an integer, but the property itself expects float type. This fixes
the place and where a floating point is already used it annotates
the value to be float, not a double.
