Open any RGB8 image (my image had vector shapes) 2. Tools->Scripts->Color Space 3. Select LabA/U16 4. Press Ok OBSERVED RESULT See the assert screenshot in the attachment
Git commit 8ebe5e92507e7d519692b5d92785dda517c4be69 by Dmitry Kazakov. Committed on 30/07/2021 at 12:31. Pushed by dkazakov into branch 'master'. Fix an assert when converting image colorspace with a pythin plugin It turns our that we can enter image->barrierLock() twice. It happens because the image may emit queued signals to the GUI in the meantime, and the GUI may call barrierLock again. E.g. in KisCanvas2::slotImageColorSpaceChanged() M +15 -6 libs/image/KisBusyWaitBroker.cpp https://invent.kde.org/graphics/krita/commit/8ebe5e92507e7d519692b5d92785dda517c4be69
