Sentry Crash Report:

Description roisto 2013-05-18 13:44:46 UTC

Application: muon-installer (2.0.0)
KDE Platform Version: 4.10.2
Qt Version: 4.8.4
Operating System: Linux 3.8.0-21-generic i686
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:
Opening Muon. Doesn't matter which (ldap) user I try. Muon window flashes and then it crashes.

I use normal Kubuntu 13.4. I've tried to install Kubuntu all over again, but still no with this environment.

- Custom settings of the application:
The workstation is maintained with Puppet. It uses nscd for openldap authentication. No tweaks are made to Muon.

I'm trying to create corporate workstation default so this is important to get fixed.

The crash can be reproduced every time.

-- Backtrace:
Application: Muon-sovellusvalikoima (muon-installer), signal: Segmentation fault
