Hi all

I'm testing my GIl ensured version of VTK (
https://gitlab.kitware.com/vtk/vtk/merge_requests/582) with the buildbots,
and i have only three problematic recurring tests, on a specific build of
megas.

the error look like :

=========================================================

=========================================================

So it may be related to my fiddling with python.


But i'm unable to reproduce it manually on megas.

What I have done so far :
- Tests using the buildbots, you can see the last batch here :
https://open.cdash.org/index.php?compare1=63&filtercount=2&field1=buildname%2Fstring&project=VTK&field2=buildstarttime%2Fdate&showfilters=0&limit=100&compare2=83&value1=6d631431&showfeed=0&value2=20151117T044431

- Accessing megas dashboards, checking my branch was checked out, checking
it was compiled already (ninja-build), executing the command line visible
in the failing test :

/home/kitware/dashboards/buildbot/vtk-megas-linux-shared-release_opengl1_python_python3_qt_qt5/build/bin/vtkpython
"--enable-bt"
"/home/kitware/dashboards/buildbot/vtk-megas-linux-shared-release_opengl1_python_python3_qt_qt5/build/Utilities/vtkTclTest2Py/rtImageTest.py"
"/home/kitware/dashboards/buildbot/vtk-megas-linux-shared-release_opengl1_python_python3_qt_qt5/source/Filters/Core/Testing/Python/probeComb.py"
"-D"
"/home/kitware/dashboards/buildbot/vtk-megas-linux-shared-release_opengl1_python_python3_qt_qt5/build/ExternalData//Testing"
"-T"
"/home/kitware/dashboards/buildbot/vtk-megas-linux-shared-release_opengl1_python_python3_qt_qt5/build/Testing/Temporary"
"-V"
"/home/kitware/dashboards/buildbot/vtk-megas-linux-shared-release_opengl1_python_python3_qt_qt5/build/ExternalData/Filters/Core/Testing/Data/Baseline/probeComb.png"
"-A"
"/home/kitware/dashboards/buildbot/vtk-megas-linux-shared-release_opengl1_python_python3_qt_qt5/build/Utilities/vtkTclTest2Py"

Which fails with an Xerror

- Executing it with DISPLAY=:0 fail on image size
- Executing it with DISPLAY=:1 simple pass the test !

- Repushing on my branch, waiting for the buildbot, same tests still fails !

May be i'm doing something not rigth here, any help apreciated.

PS: I unvoluntarly deleted the kitware crontab, but it was pointing on a
non existente file, so i supose it's ok.
