Deleting every search action in the whisker menu preferences crashes the prefereces

[Scott Cohen]

Steps to reproduce:
1. Open the Whisker Menu preferences.
2. Go to the Search Actions tab.
3. Delete all the existing entries (I did this in descending order).
4. After deleting the last one, the preference window closes.

The expected behavior is that the preference window does not close when deleting the last search action entry.

When the window closed, I also lost all changes recently made in the time the window was open. I'm just stating this here just in case the program saves periodically instead after each action.

Is this crash reproducible with version 2.1.5?

[Scott Cohen (yetoo)]

Yes.

I also did some more testing and found that just deleting a last search entry, where all others are deleted, would cause the program to crash.

*This previous testing was done in a Virtual Box virtual machine in 18.04.1 LTS with the latest updates.

[Theo Linkspfeifer (lastonestanding)]

I can confirm the crash with version 2.1.5 (18.04.1), but not with version 2.2.0 (18.10 daily).

I fixed this bug in version 2.1.6 (git commit a73783d34fb09ba89df96c7c5b1e5d63fb3949b3).

[Sean Davis (bluesabre)]

Fixed in 2.1.6. Marking as resolved.
