[ERROR] An item with the same key has already been added.

The code works perfectly, but at strange moments for me there is an error "ArgumentException: An item with the same key has already been added";
The code is very simple, there are 2 ListBox. Each of them is bound to its own ObservableCollection<BaseResearchItem>.
When I double click on ContentControl it moves BaseResearchItem from one ObservableCollection to another ObservableCollection. Everything works without errors, I can move dozens, hundreds of times from one collection to another, But sometimes this error appears.
And Yes, there is no Dictionary in my code.
More error information.

Yes, this seems the same bug as the one described here: #1607.
It will appear fixed in the next release, thanks for reporting anyway.
