It would be easy enough to rework the code to not have the asserts and check whether the shape pointer is 0, instead of asserting -- but the underlying problem is more worrying.
Confirmed. Can be reproduces If press Ctrl+E and Ctrl+Z sequentially very quickly.
I tested the D3449 diff by dmitry on the phabricator and i couldn't reproduce the issue. I tried hard to repeated undo and merge also used large brush strokes but i couldn't crash krita. however I got many waiting for the action to get completed dialog which is normal I guess
Git commit cdf5b230143d7733327adbb7ef7218afc6010b3c by Dmitry Kazakov. Committed on 07/12/2016 at 07:13. Pushed by dkazakov into branch 'krita/3.1'. Implement a feedback for barrier blocking when doing some actions Summary: Some actions should not be started before all the previous actions are finished. That is especially true for the actions that work with layers stack, like "Merge Down" and "Flatten". Now KisDelayedSaveDialog is used not only for saving, but also for waiting before doing usual actions. It also has a busy-loop timeout of 1 second before showing up, for not distracting painters from their workflow when the action is postponed only a little bit. Fixes T4593 Test Plan: Basically, the steps like in bug 372724. 1) Select multiple layers 2) Start a long stroke (1000px colorsmudge brush is a good example) 3) Press Ctrl+E ***multiple*** times quickly 4) After all the background work is finished, press Ctrl+Z There should be no crash, and the result should be somewhat expected. Repeat the same for: 1) Merge down 2) Flatten Image 3) Flatten Layer 4) Transform a layer using "Layers" menu(?)
