crash using wlc without a curve

[GoogleCodeExporter]

What steps will reproduce the problem?
1. launch hooke setting a workdir different from the hooke dir (just to
make him not load the default curve)
2. launch the "wlc" command

What is the expected output? What do you see instead?
I expect somwthing like "No data to fit." .    I get a crash with this error:

hooke: wlc
Traceback (most recent call last):
  File "hooke.py", line 626, in OnGetDisplayedPlot
    self.GetDisplayedPlot(event.dest)
  File "hooke.py", line 634, in GetDisplayedPlot
    displayed_plot=self._plot_of_dest(dest)
  File "hooke.py", line 682, in _plot_of_dest
    for aplot in self.plots:
AttributeError: 'MainWindowPlugged' object has no attribute 'plots'

Oops. The point is that the default curve is a trick to avoid this kind of 
stuff...
that is, the quickest way to deal with that is to ensure that Hooke always has 
a curve.

But users may not get it :) , so probably some kind of warning is needed.

we have the same behavior with "peaks".   To avoid this problem this control 
should
be enough:

        try:
            have_plot=self.current.curve.default_plots()[0]
        except:
            print "No curve available."
            return None

Should I implement it?
