Bug#578701: kdelibs5: crash within Solid::Networking in case dbus is not available
Package: kdelibs5
Version: 4:4.3.4-3
Severity: normal
1.) sudo /etc/init.d/dbus stop
2.) kill your sessions dbus-launch process
3.) start a kde application using solid networking e.g. quassel-kde 0.6.1 - currently in sid
4.) get a stacktrace like this:
Application: Quassel IRC (quassel), signal: Segmentation fault

I had a quick look into the solid networking code.
in networking.cpp lines 48+:
void Solid::NetworkingPrivate::initialize()
{
netStatus = ( Solid::Networking::Status )iface->status().value();
}
this method shall look like this:
void Solid::NetworkingPrivate::initialize()
{
if (iface->isValid())
netStatus = ( Solid::Networking::Status )iface->status().value();
}
same in lines 53+
THX alot,
Thomas
