Failed to read from D:\QlikView\Triggers\Triggers..Exception=System.NullReferenceException

[#1]

Hello,

I've getting the following error a lot in the event viewer:

Failed to read from D:\QlikView\Triggers\Triggers_65679780-32f1-4307-83e9-78b30adb91a4.xml. Exception=System.NullReferenceException: Object reference not set to an instance of an object.

   at QDSMain.AndTrigger.ReadTriggerXml(XmlReader reader)

   at QDSMain.TriggerFile.ReadTriggerXml(XmlReader reader)

   at QDSMain.Clustering.ClusterFileHandler.Read(Action`1 readXML)

Anyone know what causes it?

Thanks!
