24695	Unpredictable result when scaling or rotating an object again	GerdP	GerdP	"==== What steps will reproduce the problem?
1. Select a shape, eg a building 
2. Rotate it a bit 
3. Rotate it a bit again

==== What is the expected result?
Shape is close to the result of the first rotate action, just a bit rotated
==== What happens instead?
Shape is rotated to a completely unexpected position.
==== Please provide any additional information below. Attach a screenshot if possible.
An old bug. This is just annoying. One has to undo the first rotation and do it again. This doesn't happen with move mode, only with scale and rotation. There seems to be code to handle this but it doesn't work. Problem gets worser when I zoom to close to one node.
