Innere Ausnahme 1:
KeyNotFoundException: Der angegebene Schlüssel war nicht im Wörterbuch angegeben.`
I can reproduce the exception when switching the context of a TabControl really fast. The exception does not occur always. Switching the TabControl context slowly never results in an error. It seems to be a timing issue.
It's a bug from XAMLMarkupExtensions, an issue is already open there: XAMLMarkupExtensions/XAMLMarkupExtensions#114
