Hm... Where it crashes is in the color picker mode of the paint tool. This might be one for Dmitry, because I am lost here.

Comment 2 Halla Rempt 2016-12-22 09:35:30 UTC

Asserts exist to be confirmed...

Git commit ebfaab84a240efe7b9ba42e65ecdd346e0737007 by Dmitry Kazakov.
Committed on 12/01/2017 at 11:03.
Pushed by dkazakov into branch 'krita/3.1'.

Temporary workaround for color picker bug in the gradient tool

The proper fix would be to stop the action in KisShortcutMatcher
when the tool switches. It would really fix the bug.

I had to revert that commit; it broke shift-drag brush resizing.

Fix a crash after switching tools while running color picking

The input manager should finish the action before the tool is
switched, otherwise the tool may be left with dangling KoStrokeId
pointers and crash after the next execution.
