            Bug ID: 502371
           Summary: KDE Welcome Crash after first installation
    Classification: Applications
           Product: Welcome Center
           Version: unspecified
          Platform: Kubuntu
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: plasma-b...@kde.org
          Reporter: craigkr...@gmail.com
                CC: n...@kde.org, olib...@outlook.com
  Target Milestone: ---

Application: plasma-welcome (5.27.11)

Qt Version: 5.15.13
Frameworks Version: 5.115.0
Operating System: Linux 6.11.0-17-generic x86_64
Windowing System: X11
Distribution: Ubuntu 24.04.2 LTS
DrKonqi: 5.27.11 [KCrashBackend]

-- Information about the crash:
I installed Kubuntu 24.04.2 LTS on an encrypted ext4 partition (It's a Lenovo
Legion 5 with Win11 on a different partition). Installation went smooth until
at the end it said "install add cd-rom failed" (or something like that) error -
I have no cd-rom on the device so I did not bother. Then at first boot, KDE
Welcome crashed.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Welcome to KDE Plasma (plasma-welcome), signal: Aborted
