CRASH using the Parallel Resources

Trying to help another user I encountered the following crash, which seems 100% repeatable:

1) Create a collection based on type:(bible,clause) lang:greek and check show in parallel resources.

2) Open the LSGNT.

3) Click on the Parallel Resources button, and if you have several collections, locate and check the new one.

4) Use either the Parallel Resources button or Cmd-right arrow to try to switch to one of the resources that is type:clause visualization, not type:bible, i e Cascadia or (one of the two) Open Text.

5) Spinning beach ball ending with crash.
