I've been able to further refine this bug..

The problem appears to be when selecting an expandable queue entry (+ sign) in addition to other items in queue and then selecting delete. This will cause the client to crash.

However, if you only select items in queue which do not have a hierarchy seen yet, you can delete those multiple queue items at the same time.
