[Ksecretservice-devel] Call for help sorting out bizarre bug

[Valentin Rusu]

Hello again!

This blog post helped me to understand and fix it:
http://randomguy3.wordpress.com/2010/09/07/the-magic-of-qtdbus-and-the-propertychanged-signal/

In my case, the daemon send a signal having a QDBusVariant argument 
containing a QList<QDBusObjectPath> and Qt won't know how to un-marshall it.

And BTW, the debugger has also a problem showing empty strings in the 
QList<QDBusObjectPath>.
dbus-monitor helped a lot showing that the list actually had valid 
strings in it and pointing me to a client-side problem.
