[4.7.3] Crash when doing a specific copy/paste in UMG Widget

Hey guys,

I found a crash that I’ve been able to easily reproduce.

  1. Make a UMG Widget blueprint. Open it and make sure you’re in the Designer window.
  2. Make a button, put it under the main Canvas panel
  3. Put some text inside that button.
  4. Click on the main button (not the text) and press ctrl+C to copy it.
  5. Without clicking off of the main button, press ctrl+V, as if you’re attempting to paste it onto itself.
  6. Editor crashes every single time without fail.

I usually don’t mean to do this on purpose, but I’ve accidentally done it at least 3 times in the last day or so. It’s quite annoying, especially when I lose a tiny bit of progress due to it.

Thanks for reading!

Hello Zaggoth,

I was able to reproduce this issue on our end and after doing a bit of digging I found that this is a known issue (UE-10040). This has been reported to the developers and it has been resolved internally. This solution should be available in a future release of the engine. Thank you for your time and information.

Make it a great day
