    This problem might be solved by installing the latest version of astropy
    (currently 2.0.2).
 
+**The pipeline crashes in ``pp_calibrate`` with the following error
+message: `IndexError: too many indices for array`.**
+   Well, this is embarassing... I am familiar with this problem, but I
+   haven't found a way to solve it, yet. The problem is that Source
+   Extractor runs in ``pp_photometry`` to produce an array of aperture
+   photometry results for the curve-of-growth analysis. After that,
+   Source Extractor is supposed to run then once again using the
+   optimum aperture radius. Sometimes, this second Source Extractor
+   runs seems to fail, causing ``pp_calibrate`` to fail. A manual
+   workaround is to run ``pp_photometry`` again using the ``-aprad``
+   option and the optimum aperture derived from the last run. Running
+   ``pp_calibrate`` again will then succeed.
