Bug ID: 363695
Summary: Segmentation fault after startup of muon updater
Product: muon
Version: 2.2.0
Platform: Kubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: muon
Assignee: echidna...@kubuntu.org
Reporter: k...@contact.stratic.fr
CC: aleix...@kde.org, sit...@kde.org
Unable to launch muon updater. It always ends with a segmentation fault.
Reproducible: Always
Steps to Reproduce:
1. Launch muon updater (from launcher or command line)
Actual Results:
The window shows up. It displays the waiting animation during update process
and then it disappears (due to segmentation fault)
Expected Results:
The window should display available updates
Application: muon-updater (2.2.0)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.19.0-59-generic x86_64
Distribution: Ubuntu 14.04.4 LTS
-- Information about the crash:
- What I was doing when the application crashed:
When launching muon updater it crashes at startup (from menu or command line).
The window shows up, displays the waiting animation and then disapears.
The crash can be reproduced every time.
-- Backtrace:
Application: Muon Update Manager (muon-updater), signal: Segmentation fault
