I have the opposite problem.
I recently downloaded the latest Slim ROM (SlimKat) and tried flashing it in TWRP 2.5. This didn't work, though. On the SlimRom website it mentions to update to the latest Recovery, so I installed 184.108.40.206. It still won't flash the SlimKat ROM though, it gives the same error you mentioned:
"Error executing updater binary in zip ..."
It flashes the old SlimBean ROM successfully, but even after doing the wipe and such as it recommends, it won't flash SlimKat.
Any help would be appreciated. Thanks!

Somehow it worked when I used ClockWorkMod Recovery instead of TWRP. Maybe someone else will encounter the same thing, if so that's what worked for me.
