[Comment from a bug triager]
This bug is fixed since DBus 1.3.1. Several people reported most of the DBus related crashes in also other KDE applications are fixed with DBus 1.3.1 and 1.4.0.
- Other related KDE reports: bug 241594, bug 208921
- Upstream libdbus report: https://bugs.freedesktop.org/show_bug.cgi?id=17754
