I fear it's related to #932627.

Looking more closely, it's not clear that the bug lies in nautilus-dropbox. It's failing in a function of /usr/lib/libnautilus-extension.so.1 and while trying to free a list that is not under direct control of the extension AFAIK. Marking the bug as incomplete because I have no way to reproduce it.
