Seems like something is not checking for the number of selected listview items correctly. Under investigation, will be fixed once enough information is available.

This appaears to have been fixed in 1.6.1.

Still happens, though rarely, in 1.6.1. Needs further inspection.

Fixed for good in version 1.6.4.
