"I don't know if it's a bug or if I don't know how to switch tools, but I couldn't go back to painting after using the selection tool: whatever I did, I could only make new selections, and eventually Krita Sketch crashed. I can reproduce it every time." The first part was a glitch, the second part is a crash which happens very rarely. i have been so far unable to force it to happen. Backtrace hints at something deep in the node system, but silly me did not copy the bt the one time it did happen.
It finally happened again. So, backtrace attached.

This turned out (more or less as expected) to be a race condition, caused by an out of order change to the node system (the deselection happened too soon for the system to be able to react to it, meaning that two different threads were operating on the same data, causing horrible breakage and unpredictable behaviour). So, the fix: Make sure the deselection happens as the very next step /after/ unlocking the node system, not during the process of unlocking it. Very simple fix, not straight forward to find. Very fulfilling to do ;) Fixed in http://commits.kde.org/calligra/e467bc9b1e6cae3d63f15b69873db13f7f6431a9
Selecting color deleting them then deselecting then it cause Krita to become unresponsive then crashed.
