Summary0003895: FreeCAD segfaults when pressing "Clear All" in Measure tasks dialogue with no opened document
DescriptionWhen closing a document while the Measure dialogue is active in the Tasks tab, the dialogue is not closed and remains active. If one presses the "Clear All" button, then FreeCAD crashes with a segmentation fault.
Steps To Reproduce
  1. Create new document
  2. From the Part workbench, create a Part Cube or any other solid
  3. Press the Part_Measure_Linear or Part_Measure_Angular button
  4. The Measure dialogue appears in the Tasks tab, this is essential for the crash (if the selection is made before launching the measure tool, then the dialogue does not open)
  5. Make Selection 01 and 02 to create a measurement
  6. Close the document, but do not close the dialogue. Press "Discard" at the dialog to close the document without saving it
  7. The Measure dialogue remains in the Tasks tab in active mode.
  8. Press Clear All in the Tasks tab.
  9. Instant crash.
