Fatal error in advanced search when some panes are open

To replicate on demo from advanced search type a search string in name, expand the membership pane but don't select any criteria & hit search. I thought I might be able to replicate this on other tabs as well but I didn't hit it on activity or contribution.

I think this should be fixed in 4.4 as it is a nasty fatal on a common workflow (albeit with a less common click pattern) and I believe it is a regression in 4.4
