            Bug ID: 464746
           Summary: K3b crashes after opening a .iso file
    Classification: Applications
           Product: k3b
           Version: 22.12.1
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: k3b at kde.org
          Reporter: jonrysh at pacbell.net
                CC: michalm at jabster.pl, trueg at kde.org
  Target Milestone: ---

Application: k3b (22.12.1)

Qt Version: 5.15.8
Frameworks Version: 5.102.0
Operating System: Linux 6.1.7-200.fc37.x86_64 x86_64
Windowing System: X11
Distribution: Fedora Linux 37 (KDE Plasma)
DrKonqi: 5.26.5 [KCrashBackend]

-- Information about the crash:
I opened a .iso file. K3B reported Transferring in a pop up window; there was a
long period during which the progress meter in the popup window movded slowly,
then the pop up reported "Transferrind (Failed) Application closed
unecpectedly" and K3b crashed.

The system has been running extremely slowly before the crash, despite the fact
that there doesn't seem to be a lot of CPU activity; my (very noisy) disk has
been noisy lately. I have too many Firefox windows open, which seems to have
something to do with slow system response.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: K3b (k3b), signal: Segmentation fault
