Stripped thread on engine mount bolt

When I put the engine back in after painting the frame I just snugged up the mount bolts (it was late autumn, wasn't going to really start putting it back together till spring. Today I took out the torque wrench to button it up properly and it was all good till I got to the lower rear mount bolt. Hell if I know how it happened but I can't get the nut to tighten or loosen. The bolt and nut just spin freely through the mount hole.
There's some thread visible (1/8" or so) at the nut end and I can spin the nut both ways with my fingers while holding the bolt head in place with a wrench. First I thought I'd sheared the bolt but I can't pull it out in two pieces and if I don't hold the bolt head steady with a wrench then spinning the nut just spins the bolt head. Flummoxed I am.

HOORAY!!! That's pretty close to how I imagined the state of the thread, based on the symptoms.
