I used Atlassian JIRA for bug and issue tracking at my last job. I absolutely loved it and it was particularly easy on the eyes. My present company is using Trac instead, and while it does do all the basics, I am finding it really lacking, particularly with the inability to easily setup multiple projects and link issues. Oh, and the fact that it uses SQLLite is a bit of an issue for me to. Does anyone have any other good reasons to switch?
