Application: plasmashell (5.12.4)

Qt Version: 5.10.1
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-3-amd64 x86_64
Distribution: Debian GNU/Linux testing (buster)

-- Information about the crash:
- What I was doing when the application crashed:

Opening the application starter menu and typing in a name of an application to start. The system starts to search for the application, and Plasma crashes after 1-2 seconds, regardless of whether or not an application was found. This is reproduceable across two computers.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
