I can confirm this fix works for the following device:
ID 0cf3:3005 Atheros Communications, Inc. AR3011 Bluetooth, "Trust usb 3.0 mini usb adapter"
After re-installing the removed 1.1.2-2 version of libmtp-runtime by its updated 1.1.3.1 version by just updating/upgrading from the default precise repository, the adapter works fine!
