MyEclipse isn’t really targeted at PDE development, but to get around this, I would recommend *not* running any MyEclipse plugins (com.genuitec.*) in your launch configuration – unless you are actually developing something that works with / depends on MyEclipse?
If you edit the launch configuration, that you are using to debug, you can edit the list of Plug-ins in the Plug-ins tab.
Hope this helps.
