-- Information about the crash:
The Activities kcm does nothing to stop you from accidentally deleting the
activity you're currently using.
Steps to reproduce:
1. Create an activity
2. Switch to it
3. Go to Settings > Activities
You'll see that the trash icon for the current active activity is bright red,
waiting for you to delete it.
4. Press the Trash button of the activity you just created and Apply.
Now the desktop icons will be gone and the background will turn black- or
actually, transparent-.
5. Switch back to the Default activity with Ctrl + Q and click it. Then you'll
have this segfault.
Spectacle actually captures the black background of the desktop as transparent
rather than black. Will attach pictures next message.
The crash can be reproduced every time.
