SUMMARY When a frame is copied to the clipboard, pasting options under 'Edit' are not greyed out, but they don't work. On master there's also a SAFE_ASSERT violation message. STEPS TO REPRODUCE 1. Create a frame. 2. In the Animation timeline docker, right click on the frame and choose "copy frame" 3. Do Edit->Paste (or any other pasting option under Edit) OBSERVED RESULT On 5.2.11 the frame isn't pasted. Same on master (git 8dd1ad1) , and also the following error message appears: SAFE ASSERT (krita): "!qimage.isNull()" in file C:/builds/graphics/krita/libs/ui/kis_clipboard.cc, line 476 Please report a bug to developers! EXPECTED RESULT Either the option isn't available, or the frame is pasted SOFTWARE/OS VERSIONS Windows: 11 10.0.26100 Qt Version: 5.15.7 portable version
