I logged my vote for this bug.

Something that is *possibly* related that seemed to work for me was uninstalling openssh (both server & client pkg). Before removing that package I tried rebooting and numerous other things to get it to list my "shared folders". After removing openssh and rebooting, it immediately found my shared folders. I haven't tried repeating this, but it's just an observation.

I have also noticed that if there is more than one pc sharing folders, I am only able to browse the first pc's folders, the other pc's folders appear empty when I know they are not.
