We use Trac, with the Timing & Estimation and Scrum Burndown plugins.

Trac is, I think, friendlier to developers than to project managers,  
but our PMs do pretty well with it.  The integration of source  
control, tickets, and a wiki is incredibly valuable.  I generally do  
most ticket updates directly from my svn commit messages, which saves  
a lot of time and keeps the ticket statuses up to date.
