This bug appeared to me after I upgraded to Natty 11.04, from 64 bit version of 10.10. I tried Ivan Firago's suggestion (chmod -x /usr/bin/which) and it DID work, but since some programs need it, like firefox's lauching script, that will not solve the problem for me. Though it may be a good hint to solve the bug.
