      Description

      Since ci_hsc#396, the regular ci_hsc build has been failing with:

      [2016-07-05T23:59:53.929169Z]  FATAL: At least 95% of sources used to build the PSF are classified as stars (49 > 50): FAIL

      This error appears to be related to DM-5877: when I reverted to versions of pipe_tasks, meas_base, meas_algorithms, ip_diffim, meas_extensions_photometryKron and obs_subaru predating that ticket landing, the error vanishes.

      I note that Nate Lust reports that he does not see these failures on his (OS X) system, but I can reproduce them on Linux: we should investigate if that's just a coincidence, or if there is per-platform variation here.
