Clazy crashes with check 'install-event-filter'

Clazy crashes with check 'install-event-filter', if the event filter is set on a static QObject.
Example:

/* static */  QObject ClassX::Obj;
...
ClassX::Obj.installEventFilter(this);

Example for a simple test (in an unrealistic use case):

QObject o;
o.installEventFilter(this);

Clazy does not crash, if the code of the example above is change to:

QObject o;
(&o)->installEventFilter(this);
