I don't know if this is relevant as one doesn't spam click on the image section's refresh-button often but....

1. Open my project
2. Click on "Images"
3. Click on the refresh-button continuously, and spam-click it fast enough and it makes spine crash
   (by spam-click I mean clicking often and fast enough =)

Hmm, weird, I have 2 skeletons in my project and the one on top doesn't produce the bug, but the one below, does : O
