For posterity and in case it helps anyone else in the future: I opened a ticket for this issue on the VirtualBox bugtracker (https://www.virtualbox.org/ticket/14055) which was closed as a probable duplicate of https://www.virtualbox.org/ticket/13475 which itself was just marked fixed in the next release.
I will attempt to replicate my problems in the new release of VirtualBox and report back if I still encounter problems.
