Looks like you should be able to tip the front of the drawer up so the back clears the tab; there should be a slot in the top of the slide mechanism that will allow the drawer to tilt when things are lined up. Alternatively, bend the tab up and then bend back down when the drawer is back in.
Having to bend something isn't unusual: Craftsman drawers have a tab behind the side rail that you have to bend in to get the drawer out; then you bend it back in so it will stop after you re-install the drawer:
