test_gdalwarp.py bad checksum

[robe]

I'm setting up the new PostGIS jenkins bot on a Debian 8 running

Proj 4.9.2 and interanl JPEG and Python 2.7.10

When testing against GDAL Trunk - last test on r31068, autotest r31072 I get ths failure

 ------------ Failures ------------
Script: utilities/test_gdalwarp.py
  TEST: test_gdalwarp_28 ... fail
    line 733: Bad checksum
 ----------------------------------

Succeeded: 2993
Failed:    1 (0 blew exceptions)
Skipped:   1565
Expected fail:8
Duration:  02m10.7s
As GDAL_DOWNLOAD_TEST_DATA environment variable is not defined, 96 tests relying on data to downloaded from the Web have been skipped
As GDAL_RUN_SLOW_TESTS environment variable is not defined, 14 "slow" tests have been skipped

On irc EvenR suggested I run this using autotest/utilities/data file

<EvenR> you could try to manually run "gdalwarp -t_srs "+proj=aeqd +lat_0=45 +lon_0=90" data/w_jpeg.tiff tmp/testgdalwarp28.tif" in autotest/utilities and I could visually check the result tmp/testgdalwarp28.tif against my own, and add your checksum in the green list if it is OK

I have attached the resulting image from that run.
