There is one, simply the original traceback, that depends on the original
exception.

The issue that I am addressing here is that if there is an exception when
the data bounds are computed, the previous impolementation of the axis
locator would give a traceback on redraw. In interactive mode, e.g. in
IPyhton, this traceback was hidding the original exception because it
came afterward.
