Bug 326497

Application: muon-installer (2.0.65)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-12-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:
Kubuntu 13.10 (upgraded) 64 bit, KDE 4.11.2
I have tried to run Muon Soft Centre from a console:

USER@HOST:~$ muon-installer
QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.
QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.
USER@HOST:~$ JSonScanner::yylex - error reading from io device 
JSonScanner::yylex - error reading from io device 
KCrash: Application 'muon-installer' crashing...
KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi from kdeinit
sock_file=/home/USER/.kde/socket-HOST/kdeinit4__0
QSocketNotifier: Invalid socket 20 and type 'Read', disabling...

I've removed my .kde folder yesterday, so my user setting are failrly default. That was the first time I opened Muon Soft Centre. Installing/updating packages with Muon Package Manager works fine.

The crash can be reproduced every time.
