I'm using \fullcite to produce in-margin-note citations as per my older question. I've almost got the behavior I want, but biblatex's \fullcite command inserts a leading indent before the citation starts:

I'm using the numeric biblatex style. It's hard to generate a minimal example that generates this text because it relies on a recent version of tufte-latex, but refer to tufte-latex Issue 60.
tufte-bookclass revisions and vanilla \fullcite. I don't get the indent. – Audrey Aug 17 '11 at 13:35
