Description rafaelbneves 2019-09-11 01:58:11 UTC 
Application: plasmashell (5.16.4)

Qt Version: 5.13.0
Frameworks Version: 5.61.0
Operating System: Linux 5.2.11-1-MANJARO x86_64
Distribution: "Manjaro Linux"

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

Iḿ new to Linux in general, sorry for any mistakes in description. What I think happened is that i was trying out "activities" function. Created a new activity, and set up some favorites in aoo launcher for each activity. Done that I was ready to make use of the feature, so I deleted the test activity and set up a new one. Thats when problems started, everytime I right clock on any Icon in app launcher, plasma crashes. I think that the fact that I had diferent favorites in app launcher for each activity, and then just deleted it, created this bug, I mean, instead of deleting all traces of the of the deleted activity, this setting was left behind, leaving favorites in respect to an activity that no longer exists.

The crash can be reproduced every time.
