My company uses StarTeam for source control and CR management, but I would really like to switch to Subversion for source control. For those of you that know ClearQuest and ClearCase, StarTeam has the ability to create tickets, which can later be associated with code changes.
Are there any similar products that integrate nicely with Subversion (preferably free, but I'm not necessarily against the idea of a commercial app)? I played around with trac a while back, but I wasn't overly impressed with it.
