Crash when using bow on vehicle

Linux Mint 17 (Qiana) / ASUS Q500A / SDL / 0.C-3691-gc3588c3-dirty

I recently moved a save folder (it exists outside and is symbolically linked) to a slightly more recent version (might be my issue, was 0.C-2840-gfe66373) compiled in SDL (the save is from an ncurses version earlier). Bug is as follows:
Was traveling south in my armored motorcycle and I let go of the controls (^-v-l) to shoot a zombie with a bow. I struck the zombie once or twice and on the, I assume, final strike of death the game crashed. The error was: “*** invalid %N$ use detected ***”
