            Bug ID: 466415
           Summary: Filelight crashes with SEGFAULT when started once with
                    no disk space left
    Classification: Applications
           Product: filelight
           Version: 22.12.2
          Platform: Ubuntu
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: stephan.seitz at fau.de
                CC: martin.sandsmark at kde.org
  Target Milestone: ---

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
