Application: plasmashell (5.9.5)

Qt Version: 5.7.1
Frameworks Version: 5.33.0
Operating System: Linux 4.10.15-200.fc25.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
1. Added new panel "Application Menu Bar"
2. Added a few standard widgets (system tray and lauch menu, idk how it calls in english) to this panel
3. Tried to resize this panel, aaaand it's gone

I saw some similar posts, but they had this crash while removing panel or widgets, and no one while resizing, so i created a new one.

The crash can be reproduced sometimes.

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