Reproducible: Always
Comment 1 Halla Rempt 2016-05-14 10:46:32 UTC 
Hm, I'm not sure how to reproduce it. If there's nothing on the clipboard, I do have the ability to create a new image with the clibboard page, but that just creates a blank image for me. The crash also seems to happen right inside a color selector.
Comment 2 Scott Petrovic 2016-05-21 23:36:10 UTC 
I tried to create a new image from the clipboard and couldn't get it to crash. I tried it from Edit > Paste into new image.  I also tried it from the File > new dialog.

Is it still acting this way when you try it now Wolthera?
Comment 3 wolthera 2016-05-25 13:32:12 UTC 
Creates a blank image for me as well now.
