happened to me when i was using Sup + Alt + RightArrow to move the album pop-up in Noise to a new workspace, the main window followed so i did it again, making it crash.

I reliably get this crash on closing MyPaint after fullscreening/unfullscreening it and hiding/revealing its floating windows a few times. I'm using MyPaint 1.0.0-1 from Ubuntu repos.

Here's a screencast of the crash. It seems it doesn't happen if I have any other windows on the workspace; at least it never crashed if I had Eidete window on the same workspace or enabled displaying pressed keys in Eidete.

Still happens as of revision 227. Rev 228 seems to fix some crashes too, I'll test it as soon as it gets to PPA.
