remove likely culprit for #5493

Browse source 
@zwimer: I had to remove a different move constructor before in the same API due to a different bug that the coverage tool exposed. I was unable to reproduce the bug reported in #5493 in my environment, but the interaction with reference counting and move constructors is sufficiently opaque that I rather not have to fix more bugs introduced with move constructors in the API. I am therefore removing also this use of && and maybe this fixes #5493
