Comment 1 Lamarque V. Souza 2013-09-22 22:40:19 UTC 
This looks like a bug in Qt or your computer's memory was corrupted when the crash happened. I have just searched for a similar bug in Qt's bugtracking website and have found this one https://bugreports.qt-project.org/browse/QTBUG-26329?page=com.atlassian.jira.plugin.system.issuetabpanels:changehistory-tabpanel

I do not think I can do anything more about this bug since it happens outside a kde library.
Comment 2 Martin Koller 2013-09-23 07:18:01 UTC 
I think I had some of kded crashes when I used the kde-connect module, which is still in flux.
It's clear that without better information you can do nothing.
Let's just close this for now.
