Apologies for that, but it isn't so obvious to me. System was running overnight with VmWare virtual machine, and chrome (streaming music). In A/M, system is sluggish (e.g., seeing issues with screen repainting in browser, lots of disk thrashing). Switched to console session (Alt-F2) : htop showed Kwin at 100% (if that is at all relevant). Switched back to GUI, and was in the process of closing all applications when desktop crashed. Didn't really do anything reconizably specific to trigger crash. I've had more than one crash. Syatem is somewhat memory constrained (4Gb RAM, but overcommitted). -- Backtrace: Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".
