Indices of wrong type for NumPy 1.12+

[kwinkunks]

Since NumPy v1.12, indexing ndarray with the wrong type (e.g. a float) raises IndexError. I think that's what's happening here.

The example code:

from PyQt4.QtGui import QApplication
import segyviewlib
qapp = QApplication([])
l = segyviewlib.segyviewwidget.SegyViewWidget(fname)
l.show()

...results in:

---

IndexError                                Traceback (most recent call last)
<ipython-input-9-e587dc28b0c1> in <module>()
      2 import segyviewlib
      3 qapp = QApplication([])
----> 4 l = segyviewlib.segyviewwidget.SegyViewWidget(fname)
      5 l.show()
