Created attachment 144816 [details] Backtrace of the crash The crash happened when I was investigating a memory leak (huge RAM usage even when I had closed all GUI applications). I noticed two Gwenview processes still running despite I had closed all Gwenview windows. I right-clicked on both of them (one after another) and selected "terminate process"/SIGTERM (don't know the exact english translation). systemmonitor crashed just after clicking "terminate .." on the second process. I have attached a backtrace.
