 * Discover may crash while carrying out a variety of actions

[Test Case]

 * A specific example to reproduce the bug is type 'latte'
 in the search box and press enter.

 * Changes could possibly introduced new regressions while fixing the issues targeted. Testing seems to indicate this is not the case so far.

It'd be good to add links to the crashes in the Ubuntu Error Tracker so that the Ubuntu SRU team can use them as input when deciding to release this new package to -updates.

I been through the upstream crash bug duplicates, and where there is enough info to indicate how they triggered the crash, tried to replicate it with this bugfix release.

So far not been able to make discover crash on the issues this fixes, nor any obvious regression, so I would say this update is good to go.

I started a Kubuntu 18.04 VM with -proposed enabled.
I started Discover, and saw an update to 5.12.5.1 was available.
Applied updates. Discover suggested a re-boot, so I re-booted my VM.
After a re-boot, I started Discover again.
I typed 'latte' (without the single quotes) in the search box and pressed enter.
No Crash.

before applying update typed latte and discover crashed...

after applying update and restart computer, typed latte in discover and no crash.

Fix works here.
