I noticed some issues recently with another bug report regarding bar
charts. It seems that if the first bar (maybe even the last bar) is of zero
height, then some code somewhere doesn't properly choose the correct axes
limit. This error here might be a degenerate form of that bug.
If anything, this indicates that the bug must be somewhere between the auto
tickers and bar(). I have checked bar() itself, and I don't see any sort of
problem. There was a possible issue at around line 4694 in axes.py (at the
end of the bar() method), but I don't think that is the cause.
