Seems to be a random/rare occurrence?

This looks like one of the UI components (specifically the drop down for picking the corpus to run a pipeline over) is trying to update using a stale list of corpora and the corpora have been unloaded as you close GATE causing an the index out of bounds exception. Probably not a show stopper but would be nice to add a guard in the right place. Will be a nightmare to reproduce to check it's fixed though.
