In order to facilitate the management of bugs in Quality Center and to compensate for the lack of a Mylyn connector, I wrote my own plugin to access QC from Eclipse (via Mylyn).
Eclipse's Update (3.4.2 / 3.5) is available here: http://qcmylyn.sourceforge.net/update/
The official website is available here: http://qcmylyn.sourceforge.net/
Note: This is an alpha version and should therefore not be used in a production environment!
