Beginning a transformation using the transform tool, then attempting to switch layers without applying or cancelling the transformation causes a Segmentation Fault.
The following is output to the terminal just before the crash:
WARNING: Transform Stroke: the device is absent in cache!
Steps to Reproduce:
1. Create a document with at least 2 layers.
2. Make a selection.
3. Select the transform tool and transform the selection in some way (but don't press enter to apply the transformation).
4. Select a different layer via the layers docker.
Terminal output: "WARNING: Transform Stroke: the device is absent in cache!"
Don't crash, obviously.
(Not sure what it would do if it didn't segfault, but if there's any doubt, I suggest it should either discard the unfinished transformation, store it in some way so the user can continue transforming when they switch back to the layer, or show a dialog asking the user whether to apply/discard/cancel.)
Thank you for your report! I can reproduce this crash.

Fix a crash in the transform tool
The currentNode() can be changed when the stroke is finished
by switching the layers.
