segfault 11 on mac os when loading freecad library about theia

[bandang0]

Hi,
According to the thread 0 stack the crash occured upon loading of the FreeCAD module, right when theia imports it (lines 106-7 of theia.main.py). This also occurs on FreeCAD 0.16 if you do:

>>> import Part
>>> import FreeCAD

instead of importing FreeCAD before Part.

On FreeCAD 0.16, the segfaults are avoided by importing in the right order.

It is thus possible that, theia having been designed and tested with FreeCAD 0.16, it be (import-wise in the case of this segfault) incompatible with 0.17.

Furthermore, in FreeCAD 0.17 the release notes state important changes to the Python API:

A word of caution to users of v0.16: there has been tremendous changes to the PartDesign workbench, with the introduction of the Part and Body containers. A Body is now mandatory to create PartDesign features. When trying to edit a document made in v0.16, you will be prompted to migrate it automatically. If your model was done with a mix of PartDesign features and Part objects, the migration process will most certainly leave your model in a broken state! So if you are not willing to migrate it manually (expect having to delete some stuff and recreate it), it would be best to keep a working version of v0.16 on the side to edit your old documents

Thus it is possible that the overall approach of writing a fcstd file with the FreeCAD API is broken by this new 0.17 release, as suggested by @philippeg-ligo in another discussion.

Until further attention can be given to how to make theia compatible (import-wise and cad-interface-wise) with 0.17, I suggest you roll back to 0.16 and give it a try.

Which Linux did you use to develop theia? I want to try out theia first.
Is anybody working on theia now? I.e., will theia be updated to work with newer version of FreeCAD?

Thank you very much
