I've reproduced this on two separate computers, with multiple versions of spine, including the latest betas and some older versions as well; I'm attaching the project, in the hope that someone can pinpoint if i'm doing something wrong! Thanks!

you had the images on one skeleton and the bones on another, also the images were in the same folder as the spine project file, so I've put them in a folder, linked it correctly, moved all the bones to the skeleton where you had the images (just click and drag from one skeleton to the other), got rid of the empty skeleton and then tried to parent the attachments and it works just fine.
I think it crashed in your case because you can't parent the things present in a skeleton to things present in another skeleton. I couldn't reproduce the crash, but I've fixed your project so you can go on working (: btw lovely artwork!

About the error, I've opened an issue so that it will pop up an alert instead of crashing next time (; Spine crashes if you try to parent the attachments from one skeleton to the bones in another skeleton · #238 · EsotericSoftware/spine-editor
YES! It's the first time i've tried setting it up, which is probably why i screwed up on the skeleton; of course, it works just fine now, thanks so much, i'll go ahead and finish rigging my thing!
Great! I'm curious to see the final result, make sure to post it in the showcase section, if you don't mind!
