Operation not allowed on sorted list - System::Classes::TStringList::InsertObject

Trying to add an Amazon S3 bucket in the Login window. As soon as I select "Amazon S3" from the dropdown, I get three "Operation not allowed on sorted list" errors with the following Stack traces (in order).

WinSCP 6.0

Error message:
Operation not allowed on sorted list

I know how to reproduce the problem or the problem happens frequently enough. I wish to be contacted by the WinSCP team to help resolving the problem.
