Cause:
===========

As per the following documentation, it should be a compatibility issue between  XULRunner and Eclipse:

1). http://forums.instantiations.com/topic-11-2082.html

2). http://www.eclipse.org/swt/faq.php#browserlinux

BE 5.0.0 Studio is an Eclipse 3.4 build and depends on XULRunner 1.8.x - 1.9.0.x
>>>>>>>>>>>>>>>>>
Eclipse 3.4.x: Mozilla 1.4 GTK2 - 1.7.x GTK2 and XULRunner 1.8.x - 1.9.0.x.
>>>>>>>>>>>>>>>>>

While on Redhat 5 and later versions, the default XULRunner version might be higher than 1.9.0. Refer to the next section to find out the xulrunner version.

Resolution:
===========
To find out the xulrunner version, use the following command:

&ltxulrunner_home>/xulrunner -v

i.e.,

[root@RHEL5 xulrunner-1.9.2]# ./xulrunner -v
Mozilla XULRunner 1.9.2.13 - 20101206060035

If the version is greater than 1.0.0 you will need to install a lower version of xulrunner (1.8.x - 1.9.0.x), and add the following line in studio.ini to overcome the error.
