Description David Faure 2014-09-11 15:31:53 UTC 
Almost all KDE apps output this:
Object::connect: No such signal org::freedesktop::UPower::DeviceAdded(QDBusObjectPath)
Object::connect: No such signal org::freedesktop::UPower::DeviceRemoved(QDBusObjectPath)
due to a signal signature change.

How about
1) using QMetaObject to find out the signature of the signal
or if that fails
2) using Introspect and parsing the XML (urgh, I know).

Reproducible: Always

Steps to Reproduce:
1. https://bugs.kde.org/show_bug.cgi?id=330278 for an example
Comment 1 Lukáš Tinkl 2014-11-07 14:20:11 UTC 
Fix warning: No such signal org::freedesktop::UPower::Device...

The signature change can be detected at runtime using Qt's QMetaObject
introspection mechanism. That prevents us from emitting the two
pesky warnings at runtime, polluting our konsoles.

Google is full of that warning, and there is also:
