Let D,x be a plane curve germ. We prove that the complex Omega(circle)(log D)(x) computes the cohomology of the complement of D, x only if D is quasihomogeneous. This is a partial converse to a theorem of , which asserts that this complex does compute the cohomology of the complement, whenever D is a locally weighted homogeneous free divisor (and so in particular when D is a quasihomogeneous plane curve germ). We also give an example of a free divisor D subset of C-3 which is not locally weighted homogeneous, but for which this (second) assertion continues to hold.
