I am also having this problem. The details, below, contain spoilers.
Because of the second piece of Wensleydale in my pocket, the Cheese Sniffer will not climb to the top of the beehive (where there is another piece of Wensleydale) in the basement. I've found no means of discarding the cheese from my inventory. So it appears this leaves me at an impass.
It is simple to reproduce this problem. Once you are in control of Gromit for the second time in the game - which is after the giant bees are unleashed - but before you dispatch the bees in the cellar, follow these steps.
- Walk to Paneer's and pick up a piece of Wensleydale. (Note that, here, you can repeatedly click on the pile of cheese and you keep picking a piece up - but your inventory maxes out at 1 piece.)
- Go back to the house and throw that piece into the cellar via the trap door.
- Return to Paneer's and pick up another piece of cheese.
At this point, you've reproduced the 'cheese bug'.
