--- Comment #2 from Alexander Mentyu <notux...@gmail.com> ---
Able to reproduce this bug when dragging taskbar item in:

Distribution: KDE neon Developer Edition - Stable Branches
Plasma: 5.11.3
Frameworks: 5.41.0
Qt: 5.9.1
Kernel 4.10.0-38-generic
Type: 64-bit


Not sure if it's same or related crash.


Here is backtrace:

Application: Plasma (plasmashell), signal: Segmentation fault
