Many examples cannot be imported to GUI

Many examples cannot be imported to GUI. Different failure modes are observed.

Assertion false failed in GUI/Model/FromCore/ItemizeSample.cpp, line 375

• scatter2d/MagneticCylinders1.py !1806 (merged)

Assertion false failed in GUI/Model/FromCore/ItemizeSample.cpp, line 527

• scatter2d/CustomFormFactor.py
• scatter2d/FindPeaks.py
• scatter2d/GratingMc.py

Assertion false failed in GUI/Model/FromCore/ItemizeSample.cpp, line 173

• varia/MaterialProfileWithParticules.py

Popup error message at first attempt may be followed by segfault at second attempt (see also #643 (closed) for generic segfault problem). Scripts without "get_sample" section cause segfault at once (#645 (closed)).

added GUI Python bug labels

Maybe @s.bouayad could help us here: Try the same with all other sample scripts, and expand this issue if some more scripts fail.

I've checked every scripts of Examples folder.

Inconsistent error : Segfault error appear when you try to import 3-4 samples no matter if you deleted the previous ones and no matter through which script. (-> #643 (closed))

Assertion false is provoked by the following scripts:

scatter2d/CustomFormFactor.py Assertion false failed in GUI/Model/FromCore/ItemizeSample.cpp, line 527

scatter2d/CylindersAndPrisms.py Assertion false failed in GUI/Model/FromCore/ItemizeSample.cpp, line 375

scatter2d/FindPeaks.py Assertion false failed in GUI/Model/FromCore/ItemizeSample.cpp, line 527

scatter2d/GratingMc.py Assertion false failed in GUI/Model/FromCore/ItemizeSample.cpp, line 527

scatter2d/MagneticCylinders1.py Assertion false failed in GUI/Model/FromCore/ItemizeSample.cpp, line 375

scatter2d/MagneticCylinders2.py Assertion false failed in GUI/Model/FromCore/ItemizeSample.cpp, line 375

scatter2d/RectangularGrazing.py Assertion false failed in GUI/Model/FromCore/ItemizeSample.cpp, line 527

varia/MaterialProfileWithParticules.py Assertion false failed in GUI/Model/FromCore/ItemizeSample.cpp, line 173

@s.bouayad Thank you for the thorough investigation. The segfault is now a separate issue, #643 (closed).
