<!-- See our full bug reporting guidelines at https://inkscape.org/contribute/report-bugs/ Writing a good bug report will ensure we'll be able to help efficiently. 🙂 --> #### Summary: <!-- Summarize the issue/suggestion concisely: --> Inkscape #### Steps to reproduce: <!-- Describe what you did (step-by-step) so we can reproduce: --> - Open Inkscape - Use defaults for setup dialog/window - Click "New Document" - Open this image (File -> Open...) *file attached in attachments* - Click image - Open "Trace Bitmap..." - Choose options: - Multicolor - Detection Mode: Autotrace (slower) - Scans: 256 - Smooth: checked - Remove Background: checked - Speckles: 1000 - Smooth Corners: 1.34 - Optimize: 5.0000 - Hit "Apply" Inkscape immediately crashes. I've reproduced it like 5 times. #### What happened? When using maximum settings on Trace Bitmap, on this image, the software crashes. #### What should have happened? I would have expected it to either: a. do the trace correctly b. if my computer isn't capable for some reason, to show a warning at least.
