|Titel||core can end in endless loop if helper can't be started|
In EventHelper::flush the function EventHelper::sendNextEvent is called in a loop until a list of events has been processed. EventHelper::sendNextEvent can return before processing an event for several reasons, i.e. if the helper is not connected. In this case the core will try to re-start the helper but if that doesn't work, the core will never return from the loop in EventHelper::flush. There may be multiple other errors in the same area. A minor related problem is that if the helper has closed the socket, sendNextEvent will report an error message that has nothing to do with what actually happened. -- This also affects 1.2.8, but we will not fix this in 1.2.8 anymore. TODO: Do we need to fix this in 1.4.0?
