xulrunner and eclipse from eclipse.org

Hello,


Since the installation of the latest xulrunner, eclipse from eclipse.org 
crashes at start. The latest version (3.4) does not seems to crash BUT 
is not compatible with myeclipse.

For now we have to uninstall xulrunner and download the mozilla.org 
version of firefox.

Do you have a idea with xulrunner and eclipse does not like each other ?

regards,
