           Summary: Muon crashes when performing updates with
                    partially-installed package
           Product: kde
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: lengau at gmail.com


Application: muon-updater (1.0.90 "Bullish Bandril")
KDE Platform Version: 4.5.90 (4.6 RC1)
Qt Version: 4.7.1
Operating System: Linux 2.6.37-020637rc8-generic x86_64
Distribution: Ubuntu natty (development branch)

-- Information about the crash:
Noticed on Kubuntu 11.04 (updates were to upgrade OpenOffice to PPA version of
LibreOffice).

Steps to reproduce:
1. Wait until you have updates available and Muon update manager appears in
system tray.
2. Click "Install updates" and type your password in the policykit dialogue
3. After the software downloads (but before it starts installing), Muon crashes
(but only if a package is partially installed).

Workaround:
Run 'sudo apt-get -f install' to fix broken package.

The crash can be reproduced every time.

-- Backtrace:
Application: Muon Update Manager (muon-updater), signal: Segmentation fault
