Thanks, I replicated it another way, but it seems to be the same crash:
Will be fixed as https://www.ventismedia.com/mantis/view.php?id=16262

Same here, though i did not have to kill the taks via task manager.

steps:
[list]open EntireLIbrary>Album sub-node, in Grid view[/list]
[url]click on an album's artist name, to go to the Artists detail panel[/url]
[list]click the back button[/list]

"datasource unassigned" ... Crash requires termination by the Windows task Manager ... ie. Restart or Safe Restart don't work ... do they ever work?
