Sentry Crash Report:

Description Markus Keil 2016-03-10 21:50:01 UTC 
Application: plasmashell (5.4.2)

Qt Version: 5.4.2
Operating System: Linux 4.2.0-27-generic x86_64
Distribution: Ubuntu 15.10

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

Everytime a new session is started (only tested after reboot) when pressing the K-Button and typing an application name into the application launcher text field, the whole plasma environment seems to crash. This is a predictable behaviour and I can only guess it may be due to my personal configuration. The system was setup from scratch and the error persists since the first time using KDE 5.

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".

Comment 2 Texstar 2016-04-09 20:49:57 UTC 
This also happens on PCLinuxOS and seems to happen more often when using the 3rd Menu option ->Application Menu. 

In fact this is the only Plasma crash we've experienced so great job KDE developers!!!
Comment 3 Texstar 2016-04-10 10:04:37 UTC 
Still the same with Frameworks 5.21.0. Here is a quick video on how to make it crash. It is when the menu is expanded twice out then the pointer is moved to the main menu entry.

Your crash is different and is not related to Baloo. Please report separately with attached stacktrace.

Judging by the stacktrace I get, your crash has a same roots as the following ones:
