Clicking on info for a process que item causes a crash

For some reason the process que gets out of sync, so when you have an item that has failed, and you click on the info icon, it cannot find the item. I think they same bug also causes the process que to halt sometimes. The relevant exception text is:
Object reference not set to an instance of an object.
System.NullReferenceException: Object reference not set to an instance of an object.
