KDE uses Bugzilla, a "Defect Tracking System". Bugzilla is one of the most popular tools used in the open source development community.
Register first
To report a bug, a person must be registered for an account on KDE's Bugzilla at https://bugs.kde.org/createaccount.cgi. A valid email address is required for registration.
Only for KDE bugs
This system is only for bugs related to KDE. If the application is not part of KDE, then the report should be filed in Launchpad instead. Please see the next section, which covers filing reports concerning Launchpad.
Launchpad is an open source suite of tools that help people and teams to work together on software projects. Launchpad is used by the Ubuntu and Kubuntu Projects, as well as various other open source projects.

To report a bug, a person must be registered for an account on Launchpad at https://launchpad.net/+login. A valid email address is required for registration.
For any bug in Kubuntu
Launchpad can be used to file a bug report for any application available in the Ubuntu or Kubuntu repositories. If the report is for a KDE application, the KDE Bug Tracking system (above) is preferred.
