Do you have seen that error before, and how would you troubleshoot it?

Answer 1

If this is like bug 223756, it could be related to where Eclipse has been installed.
May be your crash relate to read-only installation? (bug 216066, bug 225257)
Yes, that sounds reasonable. My eclipse installation resides in /opt/eclipse,
where a 'normal' user doesn't have write access..
