When I come back, all I found is my plasma crash (Plasma has crashed four times in a row in these four days...And all of them seemed to occur randomly), all of the windows' title bars disappeared, displaying was broken. After a while, KDE seemed to restart itself. Then, the KDE bug report's window "Application: Nepomuk Service Stub (nepomukservicestub), signal: Aborted" popuped "CONTINUALLY", even if I close it, it popup another same one. I have close about 20 times in total. - Unusual behavior I noticed: Then, the KDE bug report's window "Application: Nepomuk Service Stub (nepomukservicestub), signal: Aborted" popuped "CONTINUALLY", even if I close it, it popup another same one. I have close about 20 times in total. These four days, KDE Plasma crashed 4 times, whenever it crashed, what I can do is `C-M-f1` and reboot, or if luckliy KDE would restart itself... After rebooting, CPU would be occupied for a long time: kuanyui 6390 55.0 8.7 934752 531832 ?
