Discover sometimes refuses to start if you attempt to start it after having just closed it

[Aaron Rainbolt]

Test hardware is an HP Z220 SFF Workstation, 32 GB RAM, 256 GB SSD. Testing inside Gnome Boxes, VM is using SeaBIOS, 4 GB RAM. Bug is showing up in a Kubuntu Kinetic live session with the latest ISO. Discover version is Discover 5.24.5.

Steps to reproduce:

1: Click the Discover icon on the taskbar.
2: Close Discover.
3: Click the Discover icon on the taskbar.

Expected result: Discover should launch the second time.
Actual result: Discover does not launch.

Details:

When Discover fails to launch the second time, it will continue to fail to launch over and over for some amount of time. It won't launch from the taskbar, the Application Menu, or even from the terminal (it just silently fails in the terminal). After a while, it suddenly decides to start launching again, and then it's perfectly fine with launching multiple times in quick succession.

This bug seems silly, but I've hit it (or at least something similar to it) on my physical hardware. Discover told me updates were available, I went to apply them and accidentally closed the window. I didn't manage to get it back open to apply the updates, and ended up having to use the terminal, which wasn't the end of the world, but it was annoying, and for a user who wasn't comfortable with the terminal, it might have been even more problematic.
