This is to show how much I suck at reviewing code. Look at this
massive gold nugget of garbage. Nobody on their serious mind would
have let that pass code review.
But I did. And now I deserve the punishment to deal with this.
Of course, the author didn't seem to have spared more than a fraction
of a second of their brain power to even consider what they were
doing here. But that's what code review is for - preventing garbage
like this from landing. And yet, here we are, removing an invisible
Week view from the sidebar.
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.
