Narrative:

After landing and during taxi in, cabin filled up with smoke. Cause of smoke was a cracked hydraulic line in left thrust reverser line. Because APU must be run anytime below 10000', it was hot. Hydraulic fluid spewed onto APU. Since APU intake is in tail compartment, the vaporized fluid ended up in cabin.
