https://bugs.kde.org/show_bug.cgi?id=308049 --- Comment #4 from Baokai Lei --- Slightly different situation this time: Dolphin was running in an ordinary window, showing a folder with video and image thumbnails, and screensaver was running (the normal "slideshow" screensaver). In exactly the moment I stopped the screensaver, Dolphin crashed. I could get a more detailled backtrace this time by manually installing the libglib debug package (no idea why it wasn't installed before). Take a look if it's more helpful now. Application: Dolphin (dolphin), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
