Fold a Wall operator fails with "list index out of range"

[johschmitz]

I am running FreeCAD v0.20.2 with SheetMetal Workbench v0.2.60. When I try to use the Fold a Wall operator it fails with the following error message:

21:32:41  1.0
21:32:41  Traceback (most recent call last):
  File "/home/schmitz/.local/share/FreeCAD/Mod/sheetmetal/./SheetMetalFoldCmd.py", line 260, in execute

Here a screenshots to show what I did just before clicking the button:

folding line should on selected face. It look like folding line on opposite face.

Can it not fold in both directions depending on which side the line is located?
