have an Eclipse Galileo RCP application with updates provided by an Eclipse Update Site Project put on a web server. after the update, the application fails (in particular, one of the update plugins fails). when looking at the informations about the application and clicking 'Installation Details', it can be noted that the plugin (the failing one) has a duplicate entry in the plugin list: one entry with the previous version number and the other with the updated version number.
where can the trick be?
