Application: filelight (22.12.2) Qt Version: 5.15.8 Frameworks Version: 5.103.0 Operating System: Linux 5.19.0-29-generic x86_64 Windowing System: X11 Distribution: Ubuntu Lunar Lobster (development branch) DrKonqi: 5.27.0 [KCrashBackend] -- Information about the crash: I started Filelight once when I had not a single byte left on my disk. It segfaulted on launch and all succesive launches when I created a bit of free disk failed too. It could be that one essential service stopped in the background because also plasma desktop was frozen and I had to kill and manually restart it to make it work again. Filelight, however, would still crash repeatedly in this session. The crash can be reproduced every time. -- Backtrace: Application: Filelight (filelight), signal: Segmentation fault [KCrash Handler] #4 0x00007f37b0e655c9 in ??

Does it help if you export QML_DISABLE_DISK_CACHE=1?
(In reply to Harald Sitter from comment #3) > Does it help if you export QML_DISABLE_DISK_CACHE=1? I couldn't reproduce on another system with (even after deleting qtshadercache and filling up my disk afterwards) ❯ filelight --version filelight 22.12.3 Will switch to the system where I originally had this problem
Filelight: 22.12.2 Operating System: Manjaro Linux KDE Plasma Version: 5.26.5 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 Kernel Version: 5.10.174-1-MANJARO (64-bit) Graphics Platform: X11 I ran into this same issue. Plasma also froze after trying to start filelight and I had to restart plasmashell. Even after freeing up space, filelight would still segfault on launch. I even tried reinstalling filelight from scratch (`pacman -Scc && pacman -S filelight`) and it would still segfault. (In reply to Harald Sitter from comment #3) > Does it help if you export QML_DISABLE_DISK_CACHE=1? This (temporarily) fixes it for me. After clearing the cache manually (`rm ~/.cache/KDE/filelight/qmlcache/*.qmlc`), filelight doesn't segfault anymore. I haven't tried running filelight with a full disk with QML_DISABLE_DISK_CACHE=1 though.
