Okay... My bad. I guess you are right. You can vote me down if you want. But don't be such a ... You know ? ;-) http://thefilmexperience.net/storage/1990s/pulp-square.gif?__SQUARESPACE_CACHEVERSION=1365556323391
(This time I'm joking).
In fact, my answer should have include the fact that I trully think there is no "good anarchist critique" of Emma Goldman, as far as I know, but mostly, as it has been said, against her defense of free love, or criticizing her point of view concerning prostitution (or sex work), with reactionnary arguments. Because at the time, these topics were considered much (and often still remain) "outrageous".
There is also this debate about Palestine where the trotskist Reginald Reynolds reproach Emma Goldman to not support enough the movement against zionism. To which she responded that he was giving her intentions, and explained her critique of zionism. A part of it should be read here : http://theanarchistlibrary.org/library/emma-goldman-on-zionism
I heard she also was often reproached to be some kind of "petit-bourgeois" woman, centered on "lifestyle" questions, etc (Even it's pretty obvious that she wasn't when you know her life and read her works). It's a funny thing that it's still something that is often shouted against people as ad hominem attack (even not very argumented) against feminists or women in general, but also against anarchists who are not following the "majority policy" of anarchist backgrounds or organisations.
May I include this comment in my answer ? So it would be better as an answer ? ;-)
