[Telepathy] problem when QDBus invoke "GetParameters" function of telepathy-sofiasip

[Andre Moreira Magalhaes]

The code seems ok, except it's missing qRegisterMetatype for 
ParametersDefinition/List. You can also try TelepathyQt4 
ConnectionManager API, it does that for you, and also reads from manager 
file if available.
