Application: plasmashell (5.12.4)

Qt Version: 5.10.1
Frameworks Version: 5.44.0
Operating System: Linux 4.16.0-1-amd64 x86_64
Distribution: Debian GNU/Linux testing (buster)

-- Information about the crash:
- What I was doing when the application crashed:When typing to search for something in the Application menu, after three letters is crashes. After the 3rd crash in a row, the bottom panel will not recover. If I type one or two letters is works as expected.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
