[Bug 1587531] [NEW] comic applet crashes plasma 5 desktop on order of the stick

[David Talmage]

Public bug reported:

The comic applet can display Order of the Stick.  The Plasma 5 desktop
crashes when you view the most recent edition of this comic and you
click the next-comic button.

What I expected: 
I expect the comic applet to do nothing when I click the next-comic button and there is no newer comic.  I do not expect the desktop to crash.

To reproduce:

1. Add the comic applet to your desktop.
2. Load The Order of the Stick.
3. Display the most recent comic.
4. Click the previous-comic button.
5. Click the next-comic button.  
   You should see the most recent comic.
6. Click the next-comic button again.  
   The screen will turn black.
   The panel will be gone.
   You won't be able to switch activities or desktops.
   Other applications will remain running.
