...a sometimes null object with an error
Python code, file `src/Mod/Part/CompoundTools/Explode.py`
The `explodeCompound` function can be called in a context without assigning the `ViewObject` property, for example from a command line script.
The error that is fixed by this patch.

Fix#004421https://tracker.freecadweb.org/view.php?id=4421
When profiling open edges, the user must currently select a top edge and then set the Final Depth manually to a value below the selected edge(s).
This fix provides the user with feedback for the empty path generated.
Fix error when working with selections containing edges and faces. This fix effectively processes edges and only passes faces on to next processing step. This simplifies the code a bit and changes some `obj.Base` references to `otherBase` to improve readability.
Path: Improve `obj.Base` reading and processing
`obj.Base` is first read in `self._processEdges()`. All edges are identified and processed there. Remaining features are saved in `remainingObjBaseFeatures` to be processed in the next section of the Profile code.
Path: Change `if` to `elif`
This fixes error when attempting to profile loop of vertical faces, thus maintaining original Profile Faces behavior by default for vertical looped face set.
After pull request https://github.com/FreeCAD/FreeCAD/pull/4215 it
doesn't make much sense helping the user to write expressions without
leading '=', as that content will be parsed as a string.
This change adjusts the behaviour in SpreadsheetGui's LineEdit to avoid
popping up the ExpressionCompleter when no leading equal sign is used.
