Drupal 7 Bugtracker module?

I need a Bugtracker / Issuetracker module for Drupal 7. All i've found is Support Ticketing System. But its a bit buggy, always tells me "You must select a client" (user rights are configured开发者_如何学C properly, dont ask ;-).

Is there any alternative to it?

Did you try the project module and project issue module yet?

In addition to project modules, you can also try Case Tracker module.
