It doesn't happen all the time, but most of the time the Desktop Layout is changed. A similar crash occurs with panelspacer.cpp, but a single line addition from another KDE Developer fixed panelspacer.cpp's crash-causing, now leaving systemtray.cpp, and rarely shell instead, to be the one causing the crashes instead. The crash can be reproduced sometimes. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault [New LWP 77439] [New LWP 77560] [New LWP 77562] [New LWP 77443] [New LWP 77444] [New LWP 77449] [New LWP 77482] [New LWP 77460] [New LWP 77561] [New LWP 77442] [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
