Certain LPE stacks interact poorly (e.g. Powerstroke then Corners)
Steps to reproduce:
Create new document
Use pen to create a line with three points forming acute angle
Insert Power Stroke path effect
Insert Fillet/Chamfer path effect
Pick Edit tool(F2) and select the corner point/node.
Try to drag.
Sometimes the node starts gravitating towards top-left corner.
Sometimes it seems to attempt to create infinite number of green fillet points and crashes. YMMW
Applying Power Stroke after Fillet/Chamfer works better but the stroke isn't smooth.
Same happens with Pattern Along Path.
With Taper Stroke it doesn't crash but with multiple fillet points doesn't work right either.
