Issue-tracking software suggestions needed.

[reddragdiva]

At work, we use Remedy, and it's crap. We want something better.

We want to keep track of a combination of quick fixes needed, larger issues, short projects, long projects and open-ended projects. Bugzilla fits this perfectly — except the customers would like to be able to watch issues in progress. So we need something we can write the awful truth in without customers seeing anything unsuitable for their consumption. Ideally we'd like something that's as suitable as Bugzilla for us and will give a safely sanitised version accessible to the customer. (Possibly a forked version of Bugzilla.)

Suggestions from those who've used something suitable or almost-suitable are welcomed. Oh, and it has to be free, of course, because we spent our money on Remedy.
