And yet Ubuntu 18.04 has the same Qt4 library version as buster, and no bug here.

If I may, the screenshoot seems to show that the normals to the bspline could not be calculated.

This can be because we pass the wrong parameters to OCCT, OCCT has a bug somewhere or I made a bug when I wrote that routine one year ago.

If it ever happens and you have a file where it can be reproduced, just ping me and give me the file. I am more than happy to look into it.

Hi Abdullah, could you get the file attached a few posts back to fail at all? I am just curious.
