While the Virtualbox Manager is open, it sometimes will show as two icons grouped together instead of a single Virtualbox icon. Shortly after attempting to use the application, plasma desktop crashes and restores with only one Virtualbox icon. I'm using Antergos (Arch Linux) with the latest stable KDE packages. The crash can be reproduced every time. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".
