Bug#1145107: src:netgen: netgen 6.2.2605 introduced a breaking change for FreeCAD (API refactored)

[Tobias Frost]

Package: netgen
Version: 6.2.2606+dfsg1-1
Severity: important
Control: affects -1 src:freecad

Hi,

netgen has refactored in 6.2.2605 the Segments interface [1].
Unfortuntatly FreeCAD is using this interface for salmonmesh,
therefore causing FTBFS. This (I believe) has been reported upstream as [2].
Unfortuntaly I could only come up with an partial fix, see [2].

I can disable the netgen plugin in FreeCAD, but this will lose
functionality. 

Do you have an idea how to solve the issue?

Would it be a possiblity to revert the upload to 2604 until FreeCAD
upstream has found an solution?
